Tea is the most consumed beverages after water. In Terai and Dooars region of sub Himalayan West Bengal, India, tea plantations are around 150 years. Exploitation of tea garden soil over centuries has led to decline in soil fertility and crop productivity after all initiatives of external inputs. As nutrients play a crucial role in quality and quantity of manufactured tea, the present initiative has been designed to quantify the soil nutrient status of tea growing Terai and Dooars region. 79.62% (Terai) and 84.72% (Dooars) of the soil samples were found to have normal pH. 47.21% (Terai) and 49.3% (Dooars) of soil samples was found to have normal organic carbon. 12.03% and 20.82% of soil from Terai and Dooars showed low total nitrogen. Both the organic carbon and nitrogen in soil are positively correlated. Phosphorus (as P2O5) content of soil is extremely site and depth specific. Almost all samples of the study area showed high potassium (as K2O) content. Monoculture, change in rainfall pattern and inorganic additives have contributed enormous stress to soil but despite of all these odds the overall nutritional richness of these tea growing regions seems to be satisfactory.

Coffee growing areas in Andhra Pradesh and Orissa (non-traditional area - NTA) are characterized by undulating topography with terraced slopes having narrow valleys with scattered coffee farms across the elevation of the Eastern Ghats of Vishakhapatnam (Andhra Pradesh) and Koraput (Orissa) districts. Under this situation plant available nutrients will become non-available and the nutrients are stored in several pools as inorganic and organic forms in soil exchange complex are very much essential for coffee plants for its growth and development. Hence, a study was conducted to know the soil nutrient status of coffee growing region of NTA. A total of 693 surface soil samples were collected at depth of 22cm randomly from each coffee growing mandals of NTA and assessed the nutrient status (soil pH, OC, available P and K) at Regional Coffee Research Station, Narsipatnam. Results of the soil test results indicated that most of the Arabica coffee soils of NTA are acidic in reaction (72 %) and soil pH > 6.0 in these soils was 28 % in the tested soils. Plant available phosphorous (P) in the soil is low with 33 % soils and 46 % of the soils are medium in range. However, only 21 % of the soils tested are high in available phosphorous content in these soils. The majority of the soils of this region are high in available potassium about 54 % and 31 % of the soils are medium in range but only 15 % of the soils are low in available K status. Coffee soils of NTA are rich in organic carbon status and almost 47 %. 33 % of the tested soils are medium in range but 19 % of soils were low in organic carbon status. Soils are slightly acidic in reaction and were rich in organic carbon and available potassium status.

Fertility Status

Potato is a staple food crop in high hills and mountains and a major vegetable throughout the country and one of the most important cash generating crops in Nepal. With the efforts undertaken by research and extension sectors, its productivity has significantly increased in last twenty years. However, this is not sufficient for increasing population of the country. Considering its potentiality for income, employment, industrial products, export and processing, appropriate technologies are urgent.Soil fertility evaluation is the most basic decision making tool for the sustainable soil nutrient management. Soil fertility studies and mapping is an effective way to diagnose soil status and recommend as per the need of the nutrient to particular crop in the area. This research aims to assess and prepare soil nutrient map of potato super zone, Kavrepalanchowk in Nepal. The specific objectives of the research were to assess soil texture, pH and organic matter status and simultaneously prepare soil fertility map of the potato super zone. A total of 202 soil samples were collected and nutrients were analyzed using standard procedure in the soil laboratory. Composite soil samples were collected from 6 to 10 different spots of the area at 0-20 cm depth by using soil auger. The GPS location of each soil sampling point was noted. The soil sampling point of each zone was determined by studying various aspects (area, slope, colour, texture, etc.) of the study area. Based on the nutrient status, nutrient maps were prepared and presented. Soil fertility maps were prepared by observing the critical nutrients required for the specific crops and by giving those nutrients certain ranking based on the nutrients role for the crop. The soil of Potato super zone was mostly found to be silty loam, moderately acidic (pH 5.9), medium in organic matter content (2.67%) and total nitrogen (0.13%), high in available phosphorus content (56 kg/ha) and available potassium (356kg/ha). There is also sandy loam, loam and silty clay loam types of soil in the area. Soil fertility maps were prepared by setting criteria based on nutrient status that were tested in the laboratory and on the basis of nutrients that are critical for each crops of the super zones. Vegetable super zone soil was found having medium (50%) and high (30%) fertility status. Based on the soil analysis report, it could be concluded that the soils of potato super zone is fair enough for cultivating potato crop at the moment.

A field experiment was carried out on cowpea (Vigna unguiculata (L.) variety Kashi Kanchan during summer season at the experimental farm, department of Vegetable Science, College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh. The experiment was laid out in factorial complete randomized block design with 12 treatments i.e. three levels of phosphorus [control 0 kg(P0), 20 kg (P1) and 40 kg (P2) /ha] and four levels of bio-fertilizer [control (B0), Rhizobium10 ml/kg seed(B1), PSB 10 ml/kg seed (B2) and Rhizobium + PSB both 10 ml/kg seed (B3)] with three replications. The uniform dose of nitrogen (N) and potassium (K) @ 20 kg/ha along with 10 t/ha FYM (Farm Yard Manure) were applied to all the treatments. Result indicated that the application of P2 (40 kg P/ha) significantly increased the plant height, leaf area index, stem girth, number of nodules per plant, number of branches per plant , total dry matter, pod yield, available soil nutrient status viz., pH, N, P, K, organic carbon and NPK content in plant after harvesting. Similarly, seed inoculation with B3 (Rhizobium + PSB) significantly enhanced the growth, yield, soil nutrient status and nutrient content in plant over single inoculation of Rhizobium and PSB. Combined inoculation of seed with Rhizobium + PSB (B3) along with 40 kg P/ha (P2) significantly increased the stem girth (1.84 cm), total dry matter (13.91g/plant), green pod yield (196.37g/plant and 120.90q/ha), soil nutrient status viz., pH(6.20), available N (370.89 kg/ha), available P (38.57 kg/ha), available K (168.77 kg/ha), organic carbon (2.80%) and N, P and K (0.17%, 0.16% and 0.39%) content over rest of treatment combination.

Soil Fertility Status

The present study was undertaken to quantify changes in the status of soil nutrients, their depletion and build-up after continuous long intensive cropping for last 36 years in a permanent manorial trial which has been in progress since 1972 in an alfisol of western Himalayas. The rotation was maize-wheat which included various combinations of N, P, K, Zn and FYM (farmyard manure). Continuous cultivation influenced pH, OC (organic carbon), available N (nitrogen), P (phosphorus) and K (potassium). An increase in the status of organic carbon was observed in 100% NPK + FYM treatments for more than three decades from initial value of 7.9 to 12.0 g/kg. The use of either FYM or lime alongwith 100% NPK sustained crop productivity or improved nutrient status. However, imbalanced use of nutrients i.e. NP or N alone is adversely affecting the fertility of soil by aggravating the problem of soil acidity. Application of S free P fertilizer DAP (diammonium phosphate) drastically reduced the yield of both the crops. Thus, continuous use of balanced fertilizers is necessary for sustaining soil fertility and productivity of crops.

Mohr, R., Nelson, A., Tomasiewicz, D., McLaren, D., Monreal, M., Irvine, B., Khakbazan, M., Moulin, A., Derksen, D. and Volkmar, K. 2015. Nutrient status and crop productivity following a 14-year irrigated potato rotation study. Can. J. Plant Sci. 95: 351–360. Well-managed crop rotations contribute to high productivity and quality in subsequent crops, and neither excessively deplete nor increase soil nutrient levels. A field experiment was conducted in the year following completion of a 14-yr irrigated potato (Solanum tuberosum L.) rotation study to assess the impact of preceding rotation on soil P, K and micronutrient concentrations, and on soybean (Glycine max) productivity, yield and seed nutrient levels. Soybean was grown on six established rotations [potato with canola (PC), wheat (PW), canola–wheat (PCW), oat-wheat (POW), wheat–canola–wheat (PWCW), and canola underseeded to alfalfa–alfalfa–alfalfa (PCAA)] arranged in a randomized complete block design (RCBD) with four replicates. Soil nutrient levels fell within ranges typical of the region, as did soybean yield and quality. Lower P and K concentrations in spring soil samples, and in soybean seeds, were typically associated with PCAA, suggesting that fertilizer additions did not account for high rates of P and K removal by alfalfa hay in this rotation. While preceding rotation had minimal effects on soil Cu and Zn, soybean established after PCAA or after potato contained comparatively higher seed Cu and Zn concentrations suggesting that including mycorrhizal crops such as potato and alfalfa in rotation may have contributed to enhanced micronutrient availability. Soybean yield was 4–6% higher following potato than canola or cereals, and 6% higher following POW than PCW. Seed protein increased and oil concentration decreased where preceding rotations included alfalfa. The limited yield differences observed may have been due, in part, to the selection of soybean as an indicator crop, which likely minimized differences among rotations arising from disease, weeds and nitrogen. These findings suggest that, with careful management of irrigated potato systems over the longer term, crop productivity and nutrient availability may be maintained within acceptable levels for agricultural production.

Study on the soil nutrient status and crop productivity under continuous use of inorganic fertilizers and amendments in an acid Alfisol after 36 years (1972-73 to 2008-09) was carried out at Palampur, HP. Results showed that application of Recommended Dose of Fertilizer (120:60:40 kg/ha to maize and 120:60:30 kg/ha to wheat) with 10 t farmyard manure/ha applied once a year for 36 years resulted in 786 and 515 per cent increase in maize and wheat yields, respectively over control. Soil acidity rose from 5.8 to 4.58 with the application of fertilizers over 36 years. Conjoint use of FYM with 100 per cent NPK substantially improved the Organic Carbon status by 4.95 g/kg as well as available P, K and S by 154.1, 14.5 and 12.5 kg/ha, respectively in soil over its initial values, thereby indicating significant contribution towards sustaining the soil health. On the other hand, there was a drastic decline in the available N status of soil in all the treatments as compared to the initial value. The various root parameters viz., root mass density (4.08 kg m-3), root volume density (10.84 m3 m-3x10-3), root length density (2.60 m m-3 x 10-4), root surface area (204.12 m2 x 10-4) and root cation exchange capacity (8.37 c mol (p+) kg-1) were found to be highest in the plots with the application of 100% NPK + FYM. Thus, balanced use of fertilizers continuously either alone or in combination with amendments is necessary for sustaining soil fertility and productivity of crops.

In the present study, we investigated the distribution of soil available boron and its relationship with some soil properties in the samples collected from different locations in acidic alluvial soils of Cooch Behar district in West Bengal during 2013-2014. For the study about two hundred fifty (250) georeferenced surface soil samples covering 11 blocks of the districts were collected with the help of a global positioning system (GPS). The soil results revealed that pH of the analyzed samples varied from 4.91-7.28 (mean value 5.68) which indicated that soils of the district were in the acidic to slightly acidic in reaction. Organic carbon content of the soils varied from 0.42 to 1.62 % with a mean value of 0.96 % and about 93.7 % of the samples were high whereas about 5.2 and 1.2 % of the samples analyzed were in medium and low category, respectively. Results also indicated that the available B content in the soils of the districts ranged from 0.04 to 3.87 mg kg-1 with a mean value of 0.51 mg kg-1 and about 38.26 % soil samples were classified under low, whereas, 3.58 and 0.35 % samples were categorized as medium and high in available B content. It was further indicated that the content of available B in soil was positively correlated with organic carbon (r = 0.170**) and negatively correlated with pH (r = -0.021). Organic carbon status was also found to be positively and non significantly correlated with soil pH (r = 0.062). The results of the study would be immensely helpful for the extension workers to recommended B application considering pH and organic carbon status in acidic soils of the district for a profitable crop production.
