Chemical properties of soil samples

Based on soil samples collected at different depths under the forests, this study aim to: (i) analyze changes in hydrolytic acidity and humus content in the soil; (ii) evalute SOC variation; (iii) analyze changing trends in the content of easily digestible nutrients and (iv) to analyze the relationship between humus content and soil chemical properties.

Soil type is a vital determinant of soil fertility because of its characteristic biological, chemical, and physical properties. However, the soil fertility of upland soil is probably changed by different agricultural management practices regardless of soil type. This study investigated the features of soil fertility (bacterial biomass, total carbon (TC), and total nitrogen (TN)) in upland fields in Japan. One thousand soil samples from different soil types were collected from upland fields located on 36 prefectures in Japan.

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.

Distribution of available micronutrients and their relationship with different soil properties was studied in one hundred soil samples collected from different locations of 25 villages representing the soils of Garhi Tehsil of Banswara district, Rajasthan. The soils were analysed for textural separates, physico-chemical properties and status of available micronutrients. Texture of soils varied from sandy clay loamy to clay loam. On the basis of pH and EC values, these soils were found neutral to moderately alkaline and non-saline in nature.

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.

An investigation was carried out to study the soil physico-chemical properties of the sweet orange orchards in YSR district of Andhra Pradesh. To prosecute this investigation, fifty sweet orange orchards aged between 12 to 13 years were selected and soil samples were collected from these orchards at 0-30 cm and 30-60 cm depth. Soil reaction of study area varied widely. Majority of the surface soils samples (72%) were mildly alkaline, but at 30-60 cm depth 48% were strongly alkaline, 38% were moderately alkaline and 14% were mildly alkaline in pH. All the orchards were non-saline in nature.

Soil quality is one of the important factors controlling yields of the crops. Soil characterization in relation to evaluation of fertility status of the soils of an area or region is an important aspect in the context of sustainable agricultural production. Soil physicochemical parameters are more important that control its quality. Variation in nutrient supply is a natural phenomenon and some of them may be sufficient whereas others deficient.
