Soil Test Crop Response Model for Mollisols of Northern Himalayas

By · ·

A NPK ratio of 4:2:1 is considered as ideal for application of plant nutrients. However, in recent days, a huge variation from this ratio is observed due to unbalanced application of one or more plant nutrients. Production cost of N, P and K fertilizer increases day by day and the demand for them will depend upon the ability of the farmers to pay for them. Fertilizers constitute major input and increasing their efficiency will reduce cost of cultivation. Economic rationality, thus, dictates a more comprehensive approach to fertilizer application using soil tests, field experimentation for crop response and economic evaluation of the results. Fertilizer recommendations based on soil test crop response values have definitely changed the unbalanced use of fertilizer and increased the efficiency and saving of costly input of crop production. Our effort will be successful if this book could help the researchers in strengthening their understanding for conducting quality research for fertilizer recommendation.

Building Soils Naturally

By · ·

In an organic garden, plants in optimum health thrive abundantly, have harvests with amazing taste, and have the ability to fight off plant predators. When they don’t there’s often something lacking in their proper nutrition, they are missing beneficial microorganism companions, or they are short of the energy needed to reach their full nutrient-dense potential. The solution is to ”start with the soil.” But healthy soil doesn’t happen just by composting, fertilizing or companion planting alone. The solution is in Building Soils Naturally, where gardeners will find a hands-on plan of how to create productive, living soil by using a practical holistic approach – crafted right in your garden.
