The addition of biochar to soils can improve soil fertility and increase agricultural productivity. We carried out a field experiment in which biochar produced from Gliricidia sepium (Jacq.) Kunth ex Walp. was added to low-fertility Brazilian planosol and tested to increase the yield of maize (Zea mays) and snap beans (Phaseolus vulgaris L.) in sequential, organic cultivation. Biochar was applied at a 15 t/ha rate, combined or not with Azospirillum Brasiliense inoculation and organic fertilizer (Bokashi). The application of biochar resulted in an increase in soil pH and of the content of macronutrients such as phosphorus and potassium. Contrary to evidence from elsewhere, biochar had a limited effect on increasing maize yield. In the case of beans, when combined with fertilizer, biochar increased the production of beans pods and biomass, but the significant increase was observed only for inoculation. Beans are the principal component of Brazilian diet and increasing productivity of beans is of upmost importance for the poorest in Brazil, and in other tropical countries.

Fertilization is an action in plant care. Fertilization provides additional nutrients for the soil. Fertilization has a large influence on plant growth and production. Fertilization consists of organic and inorganic fertilizers. Both of these fertilizers must be balanced so that the nutrient content can be maintained properly. The use of fertilizers an organic fertilizer that is widely used, but the use of chemical fertilizers on an ongoing basis will reduce the level of soil fertility. This must be balanced with organic fertilizer. One of the organic fertilizer is guano fertilizer. This fertilizer is fertilizer made from animal waste, namely bats. This fertilizer has a very good content including nitrogen, phosphorus, and potassium. Knowledgethis fertilizer will still be low, so that an introduction and practice about guano fertilizer is needed. Therefore a community service activity was carried out on the development of the manufacture of guano fertilizer. Guano fertilizer development is carried out in the form of granules (granules). The targets of this service are vocational students who are related to agriculture. Vocational students are selected as the young generation to know about organic fertilizers and are able to contribute to the implementation of the agricultural industry. Community service activities were carried out with a presentation of the theory and practice of making guano fertilizer. As a result of this activity, students learned about organic fertilizer, namely guano fertilizer and its contents, nutrient content in the soil, balance in maintaining nutrient content in the soil, the practice of making guano fertilizer, and the creation of granule form from guano fertilizer.

Our study aims at improving the nutritional quality of eggplant fruits through application of organic fertilization. The study was conducted in Bingerville (located in the south of Côte d'Ivoire and west of Abidjan city), from April to August 2019. The work consisted in assessing, in a randomized complete block design, the effects of five manures on the biochemical parameters of Kalenda eggplant (Solanum melongena L.) fruits. The manures studied were T1: chicken manure, T2: chicken manure + plantain peel compost, T3: chicken manure + plantain peel potash, T4: plantain peel compost, T0: no fertilizer, T5 (positive control): NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4). The results showed that fiber, protein, lipid, sodium and iron contents were not influenced by the different treatments. However, treatments T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)), T4 (plantain peel compost), T3 (chicken manure + plantain peel potash) and T2 (chicken manure + plantain peel compost) induced the highest carbohydrate and energy content of fruits. With respect to phosphorus and potassium, treatments T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)), T4 (plantain peel compost) and T3 (chicken manure + plantain peel potash) had higher phosphorus values than those of other fertilizers T2 (chicken manure + plantain peel compost), T1 (chicken manure) with an average of 27; 26.58 and 25.491 mg per 100 g FM, respectively. Plants grown on the sites fertilized with chemical treatment T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)) produced the fruits richest in potassium with an average equal to 255.16 mg per 100 g FM, followed by treatment T3 (chicken manure + plantain peel potash) (245.5 mg/100g FM). For magnesium and calcium, treatments T3 (chicken manure + plantain peel potash) and T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)) were characterized by the lowest contents, thus reflecting an antagonism between potassium and these minerals. From this study, it appears that plantain peel applied as an organic fertilizer on eggplant is a source of potassium, phosphorus, carbohydrates and energy for a good nutritional balance of the body.

The article presents the results of research on the optimization of the supply of maize plants with the main nutrients under different agrochemical loads in the Forest-Steppe. The aim of the research was to establish the effect of different doses of mineral fertilizers and by-products of the predecessor as fertilizers on the supply of plants with nitrogen, phosphorus and potassium and corn yield. The research was carried out during 2016-2019 on dark gray wooded soil of the Forest-Steppe with the use of field, chemical, calculation-weight and mathematical-statistical methods. It were found that long-term growing of agricultural crops for 30 years under different agrochemical loading in crop rotation on dark gray wooded soil of the Forest-Steppe led to the creation of different agrochemical backgrounds. According to the results of soil and plant diagnostics, it has been established that nitrogen is the limiting nutrient for growing corn. In the variants with application of increased (N180P120K180) and high (N240P120K240) norms of mineral fertilizers against the background of by-products of the predecessor (winter wheat straw), where the highest yield of corn is formed - 11.21-12.10 t / ha, mobile phosphorus content 20 cm layer of soil was very high, mobile potassium - high, easily hydrolyzed nitrogen - very low. In these variants, maize plants in stages BBCH 16, 19 and 65 accumulated the optimal amount of nitrogen, and the content of phosphorus and potassium showed optimal and high supply during the growing season for the application of mineral fertilizers in the norms above N60P45K60.According to the results of correlation and regression analysis, the decisive role of nitrogen and potassium in the formation of corn productivity was confirmed. Mathematical models have been constructed that make it possible to predict the level of maize yield depending on the content of chemical elements in the soil and plants at the early stages of BBCH development.

Cassava is a tuber of significant cultural and economic importance for family farming. However, cultivation in the northeastern region of Brazil is characterized by low productivity, resulting from cultivation in naturally marginal soil, which can cause food insecurity to farmers in the region. The objective was to evaluate the initial development of cassava using substrates derived from decomposed residue from babassu biomass, as a supplement to the soils with low natural fertility. The experiment was carried out in a greenhouse in the municipality of Chapadinha, state of Maranhão, Brazil. The treatments consisted of six inclusion levels of babassu biomass (BB) in the substrates: S0, 100% soil; S20, 20% BB + 80% soil; S40, 40% BB + 60% soil; S60, 60% BB + 40% soil; S80, 80% BB + 20% soil; and S100, 100% BB. The treatments were arranged in a completely randomized design, with four replications. The soil used in the experiment is classified as dystrophic Yellow Oxisol. At the end of the experiment, the following were evaluated: percentage of cuttings survival, leaf area, shoot length, shoot diameter, root length, root volume, aerial part dry mass and root dry mass. With the exception of the sprout diameter, the inclusion of BB in the substrates provided a significant positive effect for all analyzed variables, which demonstrates the early response capacity of cassava seedlings to the use of organic waste associated with the soil low fertility. The use of babassu biomass as an organic fertilizer improves soil fertility, stimulating the growth and development of cassava seedlings in a sustainable production system

Carbon Reduction

Revegetating abandoned peatlands plays an important role in reducing the CO2 footprint. One possibility for carbon reduction is cultivating blueberries as calcifuge plants in acidic peat soil. The aim of the experiment was to find out the effect of different fertilizers on half-highbush blueberry cultivar ‘Northblue’ growth and biochemical parameters in peatland conditions. The experiment was carried out in 2011–2015 with four organic and one mineral fertilizer, where three were composted chicken manure- and one maltose-based organic fertilizer. The soil of the experimental area belongs to the soil subgroup Fibri–Dystric Histosol with the peat layer 1.0–1.5 m deep. Organic fertilizer 4–1–2, which contained seaweed but had low phosphorus and potassium content, resulted in high yields in 2011 and 2013, with similar vegetative growth and comparable biochemical parameters as mineral fertilizer 6–14–23. The principal component analysis showed that the experimental year was more important in determining fruit parameters than the fertilizer type. However, our results indicated that the organic fertilizers are alternatives to mineral fertilizer for organic production.

Vegetation restorations of degraded meadows have been widely implemented. The evaluation of soil nutrient changes as affected by degradation is vital for efficient restorations. However, while macronutrients (nitrogen, phosphorus and potassium) have been widely investigated, sulfur (S) as one important element correlated tightly with other nutrients has not been thoroughly studied. Two studies were conducted to determine changes of sulfur as affected by degradation and elevation gradients. The results showed that available S (AS) changed non-linearly with elevation and the first principal component based on other soil nutrient variables. Soil AS depended on degradation levels and contributed substantially to the separation of meadows with different degradation levels. Moreover, AS responded stronger to changes in elevation gradients and degradation levels compared with other major nutrients. Thereby, AS could be an important nutrient responding to meadow disturbance, which should be considered in future studies on meadow soil nutrients cycling and vegetation restorations. The findings have implications for ecological restoration of degraded meadows with respect to soil nutrient management and conservations.

In this study, near-infrared spectroscopy (NIRS) was used to predict the contents of essential macro- and microelements in common bean (Phaseolus vulgaris L.) accessions of most widespread Croatian landraces. Total of 175 samples were used for the model development by modified partial least square (MPLS), principal component regression (PCR) and partial least square (PLS) techniques. Based on the coefficients of determination (R2), standard error of calibration (SEC) and error of prediction (SEP) the models developed were (i) nearly applicable for nitrogen (N) (0.89, 0.12 and 0.45 respectively), (ii) poor for iron (Fe), cinc (Zn), potassium oxide (K2O) and potassium (K), (iii) usable for phosphorus pentoxide (P2O5), phosphorus (P), phytic acid (PA) and manganese (Mn). The MPLS regression statistics suggested the most accurate models developed comparing with PLS and PCR. It was concluded that a wider set of common bean samples needs to be used for macro- and microelements prediction by NIRS.

To increase crop productivity while reducing environmental costs, an integrated soil–crop system management (ISSM) strategy was developed and successfully adopted in China. However, little information is available on the long-term ISSM effects on maize agronomic and environmental performance. Therefore, we evaluated the effects of ISSM with combining inorganic and organic fertilizers on maize productivity, N use efficiency (NUE) and N balance and losses as compared with farmers’ practice (FP) and high-yielding practice (HY), based on an 11-year field experiment in Northeast China. Maize yield in ISSM (11.7–14.3 Mg ha−1) achieved 97.7% of that in HY and was increased by 27% relative to FP. The excellent yield performance in ISSM was mainly attributed to optimum plant population structure and yield components. Annual N surplus in ISSM was only 7 kg ha−1, which was considerably lower than that in FP (52 kg ha−1) and HY (109 kg ha−1). Consequently, ISSM obtained significantly lower N losses and greenhouse gases emissions and higher NUE. In contrast to FP, crop performance in ISSM showing better sustainability and inter-annual stability. In conclusion, ISSM is an effective strategy to achieve long-term sustainable high crop yields and NUE with less environmental costs in the intensive agricultural system.
