A farmer should know the essential mineral elements and how they affect the following :- • Plant growth • Their deficiency symptoms • Methods for preventing or correcting deficiencies. I'm Tapsendra Patel and in this article, we will discuss about :- • Soil • Micro and Macronutrients • pH and its importance to the soil Soil It is commonly thought of as that portion of the earth surface derived from rock and in some cases containing organic remains which living organisms are associated. Weathering breaks rocks into smaller particles by the processes of physical disintegration and chemical decomposition. The resulting changed physical and chemical characteristics of the rock make it capable of supporting the growth of plants. The nature of a soil is dependent upon the rocks from which it was derived, but is also dependent upon the length of time and intensity of the • Chemical •Physical •Biological forces that have acted upon it. The soil in turn is the source of the essential...
There are many problems faced by farmers while tilling the soil such as improper pH, erosion, or loss of organic matter and nutrients. But one of the most serious and persistent problem over the history of agriculture, in so many of the drier regions of the world has been Salinity . View Semester Wise Subjects list of B.Sc Agriculture | Click here to view | As a broad way we can say that soils of humid regions tend to become acid, while soils of arid regions tend to become saline. I’m Tapsendra Patel and in this article we will discuss soil with it’s Salinity issues and how to overcome from this problem. Farmers in the more arid parts of the nation have a several soil related problem—an accumulation of soluble salts. This accumulation can became a major problem in dry climates where natural amount of rainfall cannot flush the salts out of the soil . • This problem can also occur with poor drainage in irrigated fields. Irrigation water imports salts into fields where t...
