This chapter, like Churchman (2000), seeks to bring readers up to date with information and
understanding about the alteration of minerals and the nature of their products in the context …

The capacity of a soil to sequester organic carbon can, in theory, be estimated as the
difference between the existing soil organic C (SOC) concentration and the SOC saturation …

Pakistan is located in the sub-tropical zone and soils are deficient in a number of plant
nutrients especially nitrogen (N) and phosphorus (P) including some micronutrients such as …

The rate of non-exchangeable K+ release from soils can significantly influence K+ fertility of
soils. There are few studies about the relationship between the kinetics of K+ release and …

Field and laboratory observations based on X-ray diffraction techniques suggest that 2: 1
clay minerals behave as a K reservoir. However, 2: 1 soil clay assemblages are most often …

Although conservation tillage has been widely implemented to address the challenge to
improve crop yield and soil quality with fewer environmental costs, its long-term effects on …

This article reviews the information regarding potassium (K) status of Indian soils based on
research conducted since 1929. The patterns and lacunae regarding potassium …

A thorough understanding of the variation in total soil element concentrations is important
especially in the Sub-Saharan Africa (SSA) soil contexts for agricultural and environmental …

Diffuse reflectance Fourier transformed mid‐infrared (DRIFT‐MIR) spectroscopy can predict
many soil properties but extractable nutrients are often predicted poorly. This paper tested …

Potassium (K), an essential plant nutrient, has long been overlooked in agriculture in many
developing countries. In most of the agroecosystems of these countries, potash balance is …
