“…Most soil fertility studies have been carried out in relation with major agronomic crops where fertilizer applications led to increased crop production (Dabin, 1961;Waller et al, 1975). This is evaluated on the basis of physicochemical properties and computed soil fertility parameters.…”

Among the greatest challenges of Sub-Saharan Africa is the need for more crop production for supplying the increasing demand of its growing population. For this purpose, knowledge on soil resources and their agricultural potentials is important for defining proper and appropriate land use and management. We thus investigated on the status of soil fertility in Tombel area, in order to produce such knowledge through understanding and monitoring the impact of physicochemical properties of soil. Diverse analyses performed on various datasets demonstrated the direct impact of physicochemical properties of soil and derived soil fertility parameters on major constraints for plant growth and optimal crop production such as water retention capacity, roots development, soils aeration, nutrients availability, nutrients abundance and cations balance. Based on physicochemical soil properties, fertility parameters and Soil Quality Index (SQI), four soil fertility classes were identified in the area: (i) very good fertility soils (66 km 2) that corresponds to Dystric Vitric Andosols (Melanic) above 500m asl; (ii) good fertility soils (506 km 2), grouping Dystric Vitric Andosols (Melanic) below 500m asl and Leptic Fragic Umbrisols; (iii) fairly good fertile soils (787 km 2) including Dystric Fragic Cambisols (Humic), Rhodic Acrisols (Cutanic Humic), Fragic Umbrisols (Arenic), and Mollic Ferralsols (Eutric Humic); (iv) poorly fertile soils (375 km 2) including Umbric Andosols (Fragic) and Umbric Pisoplinthic Plinthosols (Haplic Dystric). The principal indicators controlling soil quality in the Tombel area as derived from ANOVA and PCA analyses, are: Ca, Mg, pH water, organic matter (OM), available P, total Nitrogen and CEC. Four of the seven indicators (Ca, pH, OM, P) were also identified as important indicators for assessing the fertility status of the different soils groups in the Tombel area.

“…A number of previous investigations have been concerned with fertilizing species that are important on the tallgrass prairie, such as little bluestem, Schizachyrium scoparium (White 1961, Dickinson 1964, Nixon and McMillan 1964, Reardon and Huss 1965, van Amburg and Dodd 1970, Rao et al 1973, Senter 1975, Waller et al 1975. In other instances, fertilizers have been added to the prairie and responses have been measured in terms of yield (Gay and Dwyer 1965, McMurphy 1970, Owensby et al 1970, Hyde and Owensby 1973, Dodd and Lauenroth 1979, species com-positional changes (Huffine and Elder 1960, Owensby eta!.…”

Nitrogen cycling in tallgrass prairie was studied by using nitrogen content and concentration data for various ecosystem components on grazed and ungrazed tallgrass prairie in northeast Oklahoma. The seasonal dynamics of N in various plant parts was described, and the annual flow of N among different compartments was calculated. A simulation model was used to study the effect of grazing, fertilization, irrigation, and fire on nitrogen cycling. The results show that grazing, fertilization, and irrigation increase the nitrogen cycling rates. Annual spring fires reduce plant uptake and mineralization of N from plant parts, while mineralization of N from organic matter is increased.

Food and nutrient are holding a life of livings on the earth. From â€˜Sindâ€™ Culture to this. Modern Culture role of agriculture is same however with respective time and advance in technology as well as use of chemicals, Soil lacks her nutrient. Though the use of external chemicals result in quantitative growth of crop, but internally soil health get suffer from it and one â€“day it might be loss her fertility. Hence as we need doctors for our health, same way soil testing tools has a vital role in testing the soil for nutrient in soil and test its productivity. Use of computerization and digitization in this agriculture field give the advance features. Like Easy classification of soil on the basis of its different features and also from testing the quality of soil to suggest the additional supplement to improve the health and nutrient in the soil. Key objective of this paper is to capture soil health in concern of nutrient. In this paper, we have shown the classification approach of soil nutrient and detecting the soil health. We have built model using SVM (support vector machine) classifier. Results are compared with standard chart of soil health contains from the agriculture laboratory. Our detection accuracy lies between 95 to 99%.
