Macronutrient in soil
-
Ebook "Fundamentals of soil science (8th edition)" revision of a bestselling text shows that soil is three-dimensional and dynamic. This concept is developed in the first two chapters and is built on throughout the book. Chapters 3 through 7 explore soil physical properties and water, with expanded coverage of tillage and traffic and an increased emphasis on water and wind erosion processes. Chapters 8 through 11 discuss the biological aspects of soils as well as their mineralogical and chemical properties.

The results indicated that the climatic factors have significant role on the monthly and seasonally microhabitats. The great variety of coarse sand recorded in El-Ssabha sand dunes. Soil moisture percentage gave maximum percentage in wet season during the two years 2007 and 2008. Soil pH and soil E.C obtained varied according to the location.

Phosphorus is an important macronutrient that is severely lacking in soils. In plants, specific microRNAs (miRNAs) essential for nutrient management and the regulation of stress responses are responsible for the control of many phosphate starvation responses. Further understanding of conserved and species-specific microRNA species has potential implications for the development of crops tolerant to soils with low phosphate.

Phosphorus (P) is one of the major essential macronutrients for biological growth and metabolism of plants. Tea (Camellia sinensis L) plantation requires adequate amount of P for the proper yield of tea leaves. However, due to acidic nature of tea growing soils, phosphorus fixation is a common phenomenon. A close look at the different pools of soil P reveals, major portion of soil P is present in the form of organic P.

Soil fertility evaluation of an area is an important aspect in context of sustainable agriculture production. The macro nutrients govern the fertility of soils and control the growth and yields of crops. In the present investigation Narayanpur block was selected in the district Mirzapur of Uttar Pradesh and studied the available macronutrient status and their relationship with physico-chemical properties. Mirzapur district have different cropping systems and irrigated by Ganga canal and Tube well tributaries.

Assessment and characterization of macronutrient in soil of Kabeerdham district, Chhattisgarh, India
A survey of chemical properties of soil samples were collected from 3 Blocks. They are Kawardha, Bodla and Lohara in Kabeerdham District, Chhattisgarh was carried out in 2019-20.The main objective of this study was to collect information regarding soil chemical status, for 9 sampling points were selected.

An investigation was carried out to study the distribution of available macronutrients (N, P, K and S) and their relationship with some physico-chemical properties of soil of different blocks of district Udham Singh Nagar (Uttarakhand).The soils of the district were found sufficient in Phosphorus, Potassium and Sulphur but low in available Nitrogen content. In general the macronutrients were correlated significantly and negatively with pH and positively with organic carbon of the soil.

Micronutrients are essentially as important as macronutrients to have better growth, yield and quality in plants. The requirement of micronutrients (boron, iron, copper, zinc, manganese, magnesium and molybdenum) is only in traces, which is partly met from the soil or through chemical fertilizer or through other sources.

Present study was undertaken to evolve an efficient and reliable measure for management of sheath blight of rice through application of judicious doses of plant nutrients. In this investigation, the effect of different doses i.e. control dose (naturally available in soil), deficient dose, recommended dose and excess dose of macronutrients (N, P &K) & micronutrients (S, Zn & Fe) were assessed on incubation period for first appearance of sheath blight, disease severity and on phenolic contents in inoculated rice plants.

Plant nutrition plays a major role in quantitative and qualitative crop production in bringing sustainability and plants require seventeen essential elements for their normal growth and development. Among these, those elements required smaller in quantity is called micronutrients (Fe, Cu, Zn, Mn, B, Cl, Mo and Ni). Micronutrients are essentially as important as macronutrients to have better growth, yield and quality in plants.

Regarding yield of the crops and growth regulation fertility of soil is most important but today’s scenario of agriculture farming in India is not care about it. Without any analysis farmer used unwanted and abundant quantity of fertilizer and water, both results reduce fertility of soil. For sustainable agriculture development and production, analysis, chemical composition, micronutrient, macronutrients and micro fauna from soil is must. Soil is an important natural resource and plays a crucial role in maintaining environmental balance.

In this paper, spatial variability in soil chemical properties and fertility were investigated in Bareli watershed, Seoni district of Madhya Pradesh. Georefened soil samples with a grid spacing of 325×325 m were collected in the study area and analyzed for soil pH, organic carbon, cation exchange capacity, available macronutrients (N, P and K) and micronutrients (Fe, Mn, Cu and Zn). Spatial variability was quantified through semivariogram analysis using geostatistics and kriged maps were generated in Geographic Information System (GIS).

Phosphate is the key macronutrient required for the growth of plants. The soluble forms of phosphorus when applied to soil are rendered insoluble by undergoing chemical fixation. The soil collected from organic farm, SKUAST- Jammu was investigated for screening the phosphate solubilizing bacteria. In the present study, soil samples were collected from rice rhizosphere of sixteen varieties grown in OFRC, SKUAST- Jammu. This study revealed the existence of Phosphate Solublizing bacteria in the rhizosphere soils of rice.

Phosphorous is one of the important macronutrient along with nitrogen which limit the growth, development, and yield of the plant. The soluble forms of phosphorus when applied to soil become insoluble through chemical fixation. The Phosphate solublizing bacteria (PSB) plays a very vital role in making soluble phosphorous available to the plants. A study was undertaken in rice growing area of Jammu district, J&K, to screen the phosphate solubilizing microorganisms from the rhizosphere soil. The soil samples were collected from two rice growing blocks, R. S.
