Major and micro nutrient status of rice-chickpea grown in soilsof Chhattisgarh Plain region of India

Abstract

The content of major and micronutrients and their availability to crop vary widely depending upon soil types, nature of crops, ecology and agro climatic variability. Study undertaken to assess the nutrients status of rice-chickpea grown areas of Chhattisgarh plain region of Chhattisgarh revealed that soil were low in available nitrogen and low to medium in available phosphorous and high in potassium status. Soils are deficient in micronutrients (Fe, Mn, Zn and Cu). This problem is aggravated by the fact that many modern cultivars of major crops are highly sensitive to low micronutrient levels. Available micronutrients were negligible in Fe, Mn and Cu, but Zn status 43 percent soils sample had deficit level. However, frequency distribution of micronutrients into various categories showed that large area in the state has potential to be deficient in future, which may respond to micronutrients applications. In order to understand the geographic distribution of available micronutrient content in soil of the state, soil micronutrient maps have been developed using GPS and GIS which will improve our understanding regarding nature and extent of micronutrients deficiencies and their response to crop growth and development. These maps and frequency distribution of available macro and micronutrient content in soils will be highly useful in assessing fields scale variability for developing site-specific nutrients management for better human and livestock health of Chhattisgarh plain region.

Assessment and Comparison of Soil Quality Using Principal Components Analysis (PCA) & Expert Opinion (EO) Methods in different Rice-based Cropping Systems in Alfisol

“…ANOVA study on soil physical, chemical, and biological properties was registered better for rice legume cropping systems in terms of lower BD, higher porosity, MWD, SMC, high SOC, and available macro and micronutrient content along higher microbial activities. These all are positively correlated to significantly better SQI of rice legume cropping systems [39,40].…”

SFMToolbox: an ArcGIS Python Toolbox for Automatic Production of Maps of Soil Fertility

“…Different tasks of agricultural information systems are estimated using new technologies [17]. Macronutrients and micronutrients determine soil fertility because it is the soil's inherent capacity to provide nutrients to plants [18]. New technologies may be applied to the assessment of soil fertility for quick results [19].…”

Spatial Variability of Soil Chemical Properties in Patna, Vaishali and Saran Districts Adjoining the Ganga River, Bihar, India

“…The use of GPS devices can improve the quality and future applicability of that data for various purposes. Study of soil fertility status and mapping of pH, electrical conductivity, organic carbon, nitrogen, phosphorus, potassium, sulphur, zinc, iron, copper and manganese using GIS interface were reported from several localities (Arunkumar et al, 2016;Kumar et al, 2017;Santhi et al, 2018). Thus, the geostatistical tools are getting much more effective in soil health management.…”
