Removal of basic nutrients from the soil by field crop rotations with different fertilizers

The effect of application of different doses and combinations of mineral fertilizers in field crop rotation on the content of basic nutrients in plants, economic and relative removal of winter wheat, corn, spring barley and soybeans was studied. Soil - Luvic Chernic Phaeozem. The scheme of the experiment includes 11 variants of combinations and separate application of mineral fertilizers and, including the variant without fertilizer. It was found that the level of nitrogen content of easily hydrolyzed compounds in the soil significantly affects its content in the grain of spring barley, corn, soybeans (R2 = 0,92–0,93), less - winter wheat (R2 = 0,63). The content of mobile phosphates in the soil has almost the same effect on its content in the main and non-commodity part of the crop, regardless of the crop (R2 = 0,39–0,70). The smallest relationship between the content of mobile compounds in the soil and in the crop was in potassium, but in soybean seeds and straw of spring barley and soybeans it was clearly traced (R2 = 0,53–0,68). Nitrogen (64,4–149,9 kg / ha) has the largest share in the economic extraction of nutrients with grain and seed yield, followed by phosphorus – 21,1–51,4 kg P2O5/ ha, depending on the crop. On the formation of the crop unit of marketable and the corresponding amount of non-marketable crop products absorb nutrients in the following ratio N : P2O5 : K2O: winter wheat – 1 : 0,4: 0,7; corn – 1 : 0,3 : 0,8; spring barley – 1 : 0,4 : 0,7 and soy – 1 : 0,4 : 0,4. With the non-commodity part of the crop, nitrogen with corn stalks returns to the soil from economic removal – 28–36 %, phosphorus with soybean straw (47–54 %) and potassium with winter wheat straw and corn stalks – 74–80 %, depending on the experiment variant.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

Purpose. To establish the influence of the soybean crops protection from diseases system on reduction the degree of damage and grain yield increase in conditions of the Right-Bank Forest-Steppe zone. Methods. Field, quantitative-weight, comparative-calculation, mathematical-statistical. Results. Dependence of the effectiveness of soybean protection systems against diseases (fusarium wilt, septoria, bacteriosis) and crop rotation is revealed. Application of the system of soybean protection against diseases grown in a 4-field crop rotation reduced the incidence of plant diseases by more than 2 times compared to the control, which significantly affected the level of soybean yield. In the areas of application of the soybean protection system against the most common diseases, which consists in pre-sowing seed treatment (Rhizoactive 2.0 kg/t + Maxim XL 035FS (1.0 l/t) in combination with spraying crops with Abacus fungicide (1.5 l/ha), provided an increase in seed yield from 1.89 to 2.16 t/ha (14.3%) and from 2.32 to 2.64 t/ha (13.8%) respectively depending on 2- and 4-field soybean-corn crop rotations cultivation. Even higher yields of soybean seeds were obtained from the effects of this protection system together with twice done fertilization of soybeans with Plantafol (2.0 kg/ha). As a result, the yield of soybean seeds increased on average over 5 years by 0.27-0.65 t/ha, or 13-28%, compared with the control, where soybeans were grown without fertilization, and only pre-sowing treatment of seeds with the introduction of fungicide was carried out. Conclusions. It was found that pre-sowing seed treatment (Rhizoactive + Maxim ХL 035 FS) in combination with Abacus fungicide and Plantafol fertilization helped to increase soybean seed yield from 1.89 t/ha on the control (without seed treatment in 2-field crop rotation) to 2.76 and 2.97 t/ha when using these drugs in three-field and four-field soybean-corn crop rotations or, respectively, by 46 and 57% more.

Winter Wheat Crop

Increasing the yield of the most profitable field crops and their placement in crop rotations is an urgent problem of agriculture. The purpose of the studies is to study the productivity of grain crop rotations with various saturation of winter wheat on various power backgrounds and landscape taxons in the zone of unstable moisturizing of the Stavropol Territory. Productivity of grain crop rotations depends on the developing weather conditions, the introduction of mineral fertilizers, saturation of crop rotations with winter wheat and location in the relief. The maximum yield of grain units was observed in crop rotations with winter crops. In crop rotation with a spring barley, they were collected by 3.5–4.2 с less. The use of fertilizers increased the collection of grain units on average by 4.9–6.1 c/ha. On the outskirts of the placard (A1) due to lower soil fertility the minimum collection of grain units was obtained (20.2 с). On average (A2) and lower (A3) slopes their fee increased by 11.7 c, or 57.9%, and by 14.5 c, or 71.8%. In the first crop rotation with 60% saturation of winter wheat the maximum yield of the grain of this culture was obtained. In the second and third crop rotation with 40% grain saturation wasassembled by 6.2–6.3 c less. Putting fertilizers in a dose of N40P40K40 increased the grain collection in the first crop rotation by 4.1, in the second — by 2.2 and in the third — by2.4 c, and according to taxons: on A1 — by1.4,on A2 — by3.6 and onA3 — by 3.8 c. According to the landscape taxons, the release of grain of winter wheat differed at 7.9–10.2 c with the maximum value on the lower slope. Upon the exit of the grain and feed units on all power backgrounds, 1st and 3rd crop turns were leading, and in the exit of the grain of winter wheat — crop rotation with 3 fields of winter wheat.

Productivity Indicators

A long-term field experiment was carried out at the Experimental Station of the VDU Agriculture Academy (formerly Aleksandras Stulginskis University), Institute of Agroecosystems crop rotation collection (equipped in 1967), during 2015–2017. The soil of the Experimental site is moderately fine textured Calc(ar)i-Endohypogleyic Luvisol. The research was carried out on winter rye (Secale cereale L.) ‘Matador’, winter wheat (Triticum aestivum L.) ‘Skagen’ and 71 spring barley (Hordeum vulgare L.) ‘Orphelija’, which were sown in 8 different crop rotations after different preceding crops and rye monoculture. The aim of the experiment was to investigate the effect of long-term crop rotation combinations on testing crops yield and productivity indicators. In many cases, rye productivity indicators were lower during 50-year monocropping. The best productivity indicators were obtained by growing rye in them in grass and fallow crop sequences, and for winter wheat in fallow with vetch–oat mixture for fodder and after manure application. In rye these indicators were more dependent on the precipitation amount and the amount of the sum of temperature during the period of generative organ formation. Among these indicators and the number of productive stems, a statistically strong and medium strength correlation interaction was identified: r = 0.83, P ≤ 0.01; r = 0.90, P ≤ 0.05; r = 0.58, P ≤ 0.05; r = 0.85, P ≤ 0.01; and winter weat r = 0.87, P ≤ 0.01; r = 0.89, P ≤ 0.01. The highest winter wheat productivity was established in crop rotation after perennial grasses and leguminous crops. Crop yield in monoculture decreases, but the optimal amount of mineral fertilizers saves lower but stable yields. Spring barley is less dependent on preceding crop, so it can be grown after winter cereals. However, they are more productive when sown after row crops and in crop rotations where one of the rotation members is fertilized with organic fertilizers.

Microbiological Processes

The peculiarities of various microbiological processes at cultivation of winter wheat and pea crops in the permanent and short crop rotations were studied in stationary experiments. It was established that the cultivation of wheat in a monoculture results in intensification of consumption of soil organic matter as compared to the crop rotations: without applications mineral fertilizers on 52,2 %, with mineral fertilizers – on 77,8 %; increase of humus mineralization: without fertilizer on 111 %, with fertilizer (N60P60K60) – on 15 %; and activation of mineralization of nitrogen compounds on 100 and 60,0 %, respectively. Cultivation of peas in a monoculture was also accompanied by intensification of soil organic matter development: without the application of mineral fertilizers by 3,17 times, with mineral fertilizers – by 1,79 times; increase of humus mineralization by 1,73 and 1,88 times, respectively; and activation of mineralization of nitrogen compounds by 2,38 and 1,88 times, respectively. The decrease of humus mineralization activity in the root zone of pea plants as comparing to the wheat was at 45,7 % (monoculture), 19,2 % (crop rotation) and 46,9 % (crop rotation, NPK) levels.

Purpose. To determine the long-term effect of a complex of factors (anthropogenic and natural) on the productivity of sugar beet for a significant period and the level of pest reproduction. Study of short crop rotations. Methods. Field, laboratory, statistical. Results. The uneven distribution of precipitation during the sugar beet growing season has differently affected the efficiency of fertilizer systems and, as a consequence, the growth, development of plants and the yield of root crops. Yield of sugar beets at constant sowing on average for five years was dynamic, but its highest productivity, regardless of the fertilizer system, was in the first years of research, from 29.7 to 39.1 t/ha (on average for 1978–1982). Further cultivation in monoculture has led to yield reduction. The highest yield of sugar per hectare was also observed in the first five years, and varied in different fertilizer treatments from 4.67 to 6.22 t/ha. The lowest yield was in 1988–1992 and 1998–2002, 2.71 to 4.42 t/ha and 2.23 to 4.53 t/ha, respectively. Sugar beet yield in crop rotation was influenced by both forecrop and aftercrop. On average, during the years of research (2011–2019), the highest yield (43.0 t/ha) was obtained in the three-field crop rotation winter wheat — spring barley — sugar beet, while the lowest (41.8 t/ha) in the crop rotation sunflower — winter wheat — sugar beet, slightly higher in the four-field crop rotation soybean — winter wheat — sugar beet — corn (42.3 t/ha). The yield of sugar during continuous sowing, on average during the study period, was 3.5–5.1 t/ha, while in crop rotation it was 7.7–8.3 t/ha. According to the results of the survey of crops in the cotyledon phase, it was found that in unchanged sowing the density of common beet weevil (Bothynoderes punctiventris Germ) is quite high, 8.8 beetles/m2 (average for 2006–2008) and exceeds the harmfulness threshold (0.2–0.3 beetless/m2) several times. At this density, the damage to plant seedlings was significant. Conclusions. The yield of sugar beet is influenced by both natural and anthropogenic factors. Of the anthropogenic, in addition to fertilizers, it is important to adhere to scientifically sound crop rotation. Long-term stationary studies have shown that the cultivation of sugar beet in monoculture leads to a gradual and stable decrease in yield and, consequently, the yield of sugar per hectare. The use of mineral and organic fertilizers helps to increase yields, but not significantly. In addition to weather conditions, the yield of sugar beet in crop rotation is influenced by forecrop and aftercrop. In the studied crop rotations, the lowest yield was obtained in the crop rotation where the forecrop of beets was sunflower, and the largest yield was obtained with legumes. Observance of crop rotation affects the phytosanitary condition of sowing; therefore, in monoculture, the density of common beet weevil is much higher than threshold, which leads to additional costs.

The Right

The influence of long-term application of different doses and ratios of mineral fertilizers in field crop rotation on the content of basic nutrients in grain and straw of spring barley has been established. The study was held in the conditions of podzolic black heavy loam soil of the Right-Bank Forest-Steppe of Ukraine. The relative nutrients removal by spring barley depending on the doses of different types of fertilizers and their combinations in the field crop rotation is calculated. It is shown that the content of basic nutrients in the harvest of spring barley (grain and straw) significantly depends on the content of their mobile compounds in the soil. This is especially true of nitrogen and less of potassium. Economic removal of nutrients from the grain harvest of spring barley depends on the doses of fertilizers in the field crop rotation and the ratio of nutrients in them. The largest share is nitrogen (65–122 kg / ha), followed by K2O - 47–92 and P2O5 26–51 kg / ha. From 1 ton of grain and the corresponding amount of straw, spring barley of the Commander variety removes 19.2–22.4 kg of nitrogen, 7.8–9.2 - P2O5 and 14.0–16.8 kg of K2O from the soil, depending on the fertilizer and saturation of field crop rotation with different types of fertilizers. Straw is an important source of soil organic matter reproduction and the return of nutrients used for crop formation. Depending on the system of fertilization, 17–25% of nitrogen, 25–30% of phosphorus and 68–69% of potassium are returned to the soil with spring barley straw via economic removal. It is specified that spring barley of the Commander variety absorbs N, P2O5 and K2O in the following ratio: 1: 0,4: 0,3 to form a unit of grain yield and the corresponding amount of straw in the conditions of podzolic black heavy loam soil of the Right-Bank Forest-Steppe.

The aim of the research was to study the effect of the inclusion of different types of perennial leguminous plants as winter wheat precursors in the crop rotation on the rate of accumulation of heavy metals in the soil compared to traditional winter wheat predecessors. The objectives of the research are to develop measures to reduce the accumulation of heavy metals in agricultural soils under conditions of modern crop rotation, limited by the number of crops grown and winter wheat. The accumulations of heavy metals in soils were calculated during the cultivation of the main crops of crop rotation with intensive fertilizer. The concentration of heavy metals in the soil was determined before and after the cultivation of legume precursors. Field studies were carried out during 2013-2017. On gray podzolized medium loamy soils of the Agronomichesky Research Institute of Vinnytsia National Agrarian University. We calculated the volumes of heavy metals with optimal rates of mineral fertilizer application for the most common types of crops grown in crop rotation. Four types of perennial grasses were sown: sowing alfalfa, meadow clover, horned lamb, sainfoin and eastern goatskin. After their four years of use, winter wheat was sown. The control was the predecessors in the following sequence: winter wheat - sunflower - winter wheat - corn. Laboratory studies of the content of mobile forms of heavy metals in soil were carried out in the Vinnytsia branch of the State Center for the Protection of Soil Fertility. Analysis of soil contamination with heavy metals during fertilization of major cereals showed that the amount of mineral fertilizers is from 257 kg/ha to 571 kg/ha for ammonium nitrate, from 175 to 225 kg/ha for double superphosphate and from 58 to 75 kg/ha on potassium chloride. According to the volume of mineral fertilizers used in the cultivation of winter wheat, 1944 mg / ha of lead and 339 mg / ha of cadmium enter the soil. Of these, with ammonium nitrate - 51.4% and 7.4%, respectively, with double superphosphate - 39.6% and 41.3% and with potassium chloride - 9.0% and 51.3%. When growing corn per 1 ha with mineral fertilizers, 2357 mg of lead and 434 mg of cadmium are applied, of which with ammonium nitrate - 48.4% and 6.7%, respectively, with double superphosphate - 42% and 41% and with potassium chloride. - 9.6% and 51.8%. Cultivation of spring barley leads to the receipt of mineral fertilizers to soils 1458 mg/ha of lead and 327 mg/ha of cadmium, of which with ammonium nitrate - respectively 35.2% and 4.0%, with double superphosphate - 52.8% and 42.8% and with potassium chloride - 12.0% and 53.2%. Mineral fertilization of winter rape leads to the entry into the soil per 1 ha of 2223 mg of lead and 390 mg of cadmium, of which with ammonium nitrate - respectively 51.4% and 7.4%, with double superphosphate - 39.6% and 41% and with potassium chloride - 9.0% and 51.5%. With mineral fertilizers for growing sunflower in the soil per 1 ha gets 2073 mg of lead and 427 mg of cadmium, of which with ammonium nitrate - respectively 41.4% and 5.2%, double superphosphate - 47.8% and 42.2 % and potassium chloride - 10.8% and 52.6%. The positive effect of growing leguminous perennial herbs on the decrease in the concentration of heavy metals in the soil and grain of winter wheat has been established. Under the conditions of intensive farming by Vinnitskaya, lead and cadmium fall into the soil for the use of mineral fertilizers in accordance with 1944 mg/ha and 339 mg/ha for growing winter wheat, 2357 mg/ha and 434 mg/ha for growing corn, 1458 mg/ha and 327 mg/ha when growing spring barley, 2223 mg/ha and 390 mg/ha when growing sunflower. The four-year cultivation of perennial leguminous grasses under intensive farming reduced the concentration of lead in the soil from 1.33 to 3.2 times and cadmium from 37 to 54 times compared with cereal crops, which contributed to improving the quality of winter wheat grain by reducing the concentration of lead from 1 7 to 2.4 times and cadmium from 1.4 times to 2.1 times.
