The Knowledge of spatial-variability is critical for site specific nutrient management in soil fertility. Soil sample (149) were gotten from surface from 10 selected sites for preparing precise digital maps using point, line and polygon tools of the GIS (TNTmips 2010) software. Soil spatial variability typically defines variation in soil properties in surface soil such as fertility, pH, EC, soil organic carbon (OC), free CaCO3, mineralizable N,P2O5, K2O and S.

The study applied the soil, land and topographic data for analyzing the potentiality of land for trees /crops suitability in the Gumla district of Jharkhand, India. The remote sensing, GIS and GIS modeling techniques were used to achieve the goal. The soil fertility, soil wetness, and slope map are scientifically produced and integrated to find out the landscape suitable categories for prioritization of trees/crops scaling in the agroforestry domain. Additionally, we have examined the drift of loss of soil wetness using satellite data from monsoon to postmonsoon period up to the village level.

A study was conducted from Mandal block in Bhilwara district of Rajasthan for assess the fertility status of cultivated land soils near and far away from industries area. Soil samples were taken from cultivated fields of 52 villages (0-15 cm depth) and analyzed for their physico-chemical properties to prepare the map on the basis of nutrient status in the soil. The pH of soil samples were observed from neutral, slightly alkaline to strongly alkaline.

Usually soil fertility maps are prepared by software such as Erdas/ArcGIS. These softwares are available with high price. Non-technical persons cannot use these for the preparation of the maps of their villages and interested areas. It is possible to prepare soil fertility maps by use of MS office (word / Excel / power point). The methodology has been explained to create the maps using village land map with survey numbers in excel sheet. It is possible to create-excel-freeform-shapes-from-polygons on any map.

Studies on “Fertility mapping of soils from Hingoli and Sengaon tahsils of Hingoli district” was carried out to investigate the nutrient status of these soils. From each village five representative soil samples were collected and from each tahsil twenty villages were selected. Hundred samples were collected from each tahsil and total 200 soil samples were collected from Hingoli and Sengaon tahsil.

Knowledge of spatial variability in soil fertility is important for site specific nutrient management. In this study, spatial variability in properties that influence soil fertility such as soil organic carbon (OC), available N, available P2O5 and available K2O, secondary and micro nutrients in surface soils (0-30 cm depth) of 67 farmers' fields of Alanatha Cluster Villages, Kanakapura Taluk, Ramanagara District, Karnataka (India) were quantified and the respective thematic maps were prepared on the basis of ratings of nutrients.

Although soil fertility mapping can help to apply appropriate fertilisers and effective fertility management techniques, there is still little information about spatial variability in fertility status of soil. Therefore this study was conducted at Hingoli and Sengaon tahsils with objects of assessing fertility status. From the study area 200 soil samples were collected and analysed in laboratory for micro nutrients.

Soil is non-renewable natural resource and supports all the lives on earth. Soil nutrients are the major contributors towards soil fertility and cater to the needs of essential elements of plant. Jute is one of the important cash crops of West Bengal. Jute fibre quality is very much dependent on soil nutrients. A detailed soil nutrient status and Jute fibre quality of the Barasat-II block of North 24 Parganas District of West Bengal was investigated during 2017-18.

Geo-statistics is an important tools extensively used for analyzing the spatial variability, interpolating between point observations and ascertaining the interpolated values with specified error using a minimum number of observations. GPS based two hundred seventy two surface soil samples were collected randomly from agricultural area of Alirajpur district of Madhya Pradesh under AICRP on MSN project. Results recorded that the73.90, 26.10, 77.57, 64.71, 93.01 and 25.37 per cent soil samples were found to be deficient in N, P, K, S, Zn, and Fe respectively.

In this paper, spatial variability in soil chemical properties and fertility were investigated in Bareli watershed, Seoni district of Madhya Pradesh. Georefened soil samples with a grid spacing of 325×325 m were collected in the study area and analyzed for soil pH, organic carbon, cation exchange capacity, available macronutrients (N, P and K) and micronutrients (Fe, Mn, Cu and Zn). Spatial variability was quantified through semivariogram analysis using geostatistics and kriged maps were generated in Geographic Information System (GIS).

Two hundred and seventy (270) geo-referenced (GPS based) composite surface soil samples (0-15cm) were collected from 8 mandals of Prudential sugar factory zone, of Chittoor district, Andhra Pradesh. Soil samples were analyzed for exchangeable Ca, Mg and DTPA extractable micronutrients (Fe, Mn, Cu, Zn). The results revealed that exchangeable calcium and magnesium were ranged from 1 to 6.8 cmol (p+) kg-1 and 0.3 to 6.8 cmol (p+) kg-1 soil with a mean values of 3.43 cmol (p+) kg-1 soil and 3.44 cmol (p+) kg-1 soil respectively.

The study was carried out to know the fertility status of major nutrients in soils of Bhudargad tehsil, Kolhapur district by using GPS-GIS technology and to correlate soil properties with the available nutrients and to evaluate the fertility index of Bhudargad tehsil. The pH of soils of Bhudargad tehsil varied from 5.5 to 8.0, most of the soils were moderately acidic (50.67%) while EC of the soils varied from 0.02 to 1.48 dS m-1 , and the values were normal. The calcium carbonate content of soils of Bhudargad tehsil varied from 0.50 to 2.80 per cent.
