The nitrogen cycle is one of the most important and complex of the biogeochemical cycles. Nitrogen gas (N2) is an inert gas composed of two atoms of nitrogen linked by a very strong triple bond. Although 78 percent by volume of the atmosphere is nitrogen gas, this abundant reservoir exists in a form unusable by most plants or organisms, unless […]
Coffee Agroforestry And Zinc Solubilizing Bacteria
Zinc is a necessary micronutrient for the metabolic activities of coffee and associated multi-crops. More importantly, zinc is required by microbes to carry out many essential physiological activities. Zinc added as a micronutrient often gets fixed in the soil and is unavailable to the plant. Plants can uptake zinc as a divalent cation but only […]
Coffee And Zinc
Zinc is required in small but critical amounts, especially in plantation cops. Among the micronutrients, Zn is the most limiting nutrient associated with Plantation crops. However, the role of zinc is much debated in coffee Agroforestry, despite scientific evidence that clearly points out to the fact that zinc plays a vital role in plant metabolism […]
Calcium And Its Interaction With Fertilizers
Coffee Agroclimatic regions significantly vary in terms of soil types and rainfall patterns. The soil types are deep friable, rich in organic matter, well-drained, and slightly acidic in reaction. The rainfall varies from 1000 mm to 2500 mm. Calcium is added to coffee plantations either as lime or Dolomite. This practice is carried out once […]
Role of Calcium in Coffee Nutrition
Calcium was deemed an essential element for plant growth and development well over a hundred years ago and its importance in the growth of all the parts of plants is well documented by soil scientists and Agronomists. The mean Ca content of the earth’s crust is about 3.64%. It is usually a far greater amount […]
Role of Magnesium in Coffee Soils
In India, Coffee is cultivated in a few pockets in the States of Tamil Nadu, Karnataka, Kerala, Andhra Pradesh, and the North East. Depending on the region, coffee cultivation is subjected to different agro-climatic zones and the soil types vary from region to region. Some zones have sandy loam, others clay, and a few others […]
