Micronutrients and contaminants in the grazing and agricultural soils of Kashmir Valley, India
Ishfaq Mir
ABSTRACT:
Soil plays a critical role in determining the food nutrition at the base of the food chain, which makes it essential for food safety. This study demonstrates how micronutrient deficiencies and pollution from hazardous elements may affect crop productivity as well as human and animal health. In the Kashmir valley’s Bandipora-Ganderbal region, 200 top soils were examined to ascertain the toxicity risks and trace element deficiencies. With mean values of 44,759 ± 6072, 120 ± 23, 114 ± 18, 89 ± 22, 44 ± 8, 33 ± 7, 23 ± 4, 19 ± 4, and 11 ± 5 respectively, the concentrations (mg kg⁻¹) vary from Fe: 31,326 to 77,420, ...
The Use of Ground Rocks in Laterite Systems: An improvement to the use of Conventional Soluble Fertilizers?
Othon H. Leonardos, W. Fyfe, B. Kronberg
ABSTRACT:
The geochemistry of lateritic terrains is discussed in terms of nutrient demand in agriculture. The data presented show a dramatic depletion of virtually all nutrients when compared to crustal levels and other soil systems. Increasing world demand for food production, particularly in tropical countries where alcohol production is also needed, has forced the agriculture frontier deep into lateritic areas. As cultivation is intensified the laterite becomes more barren and a neutral recipient for the massive doses of nutrients that are to be constantly added if production is to continue. Conventi...
The potential for glacial flour to impact soil fertility, crop yield and nutrition in mountain regions
Sarah Tingey, Jemma L. Wadham, Jonathan Telling, Shannon Flynn, Jonathan R. Hawkings
ABSTRACT:
Novel sustainable agricultural strategies that enhance soil nutrients and human nutrition are crucial for meeting global food production needs. Here, we evaluate the potential of "glacial flour," a naturally crushed rock produced by glaciers known to be rich in nutrients (P, K, and micronutrients) needed for plant growth. Our proof-of-concept study, investigated soybean (<i>Glycine max.</i> var. Black jet) growth, yield, and nutrient content with soil supplementation from glacial flour sourced from Himalayan glaciers (meta-sediment gneiss ...
Rocks for Crops: Agrominerals of sub-Saharan Africa.
A productive and sustainable agricultural system is fundamental to the well being of a nation and a cornerstone of its development. In most of sub-Saharan Africa, more than 50% of the population rely on agriculture for their livelihood, which generally contributes more than 30% of the Gross Domestic Product (GDP). Agriculture is the major source of income, employment, food security and survival for the majority of the population. While agricultural production is steadily increasing in sub-Saharan Africa, the population is growing faster than food production. The result is a net decline in per-capita food production, which contributes to increased food ...
