production in Indian vertisols (Bansal and Sekhon, ). Muralidharudu et al., () reported only 8 and 11% districts as high P in India and Madhya Pradesh, respectively. Soil phosphorus exists in inorganic P and organic P forms. These P forms differ in their behavior and fate in soils (Turner et al., ). The organic P. The Vertisols are the more significant, with great areas in India (approx. × 10 5 km 2), Australia (approx. 7 × 10 5 km 2), and Sudan (approx. 5 × 10 5 km 2), while China, Ethiopia, and the USA each have approximately × 10 5 km 2. They tend to be chemically fertile, but physically they are generally very intractable; very sticky.
Phosphorus (P) adsorption capacity and its relationship with some properties of five different soil types (Fluvisols, Cambisols, Vertisols, Arenosols and Nitosols) of Tigray Region, northern Ethiopia were studied during the main cropping season in Besides, fractionation of the total soil P in to Ca-P, Fe-P and Al-P was carried out and their relationships with P adsorption characteristics. Manufacturers may add phosphorus when processing foods to thicken them, improve taste, prevent discoloration or preserve them. Check food labels to see whether any ingredients contain "phos" in the term. When trying to limit phosphorus, look for foods that don't list "phos" among the ingredients. Examples of phosphorus food additives include.
This book provides an up-to-date information on Vertisols research, and guides readers to important reference material. Four keynote papers and eight country papers and national perspectives on the management of Vertisols in Malawi, South Africa, Sudan, Tanzania, Zambia, Zimbabwe, Ghana and Ethiopia are presented. In field experiments in in the absence of P application pigeon peas produced and t DM/ha on an Alfisol and a Vertisol, resp., compared with and t, resp., in sorghum. P uptake by sorghum was greatest on the Vertisol whereas uptake by pigeonpeas was greatest on the Alfisol. These results were confirmed in pot experiments, where growth and P uptake of sorghum, soyabeans.

Most Vertisols occur in the semi-arid tropics, with an average annual rainfall sum between and mm, but Vertisols are also found in the wet tropics, e.g.
in Trinidad where the annual rainfall sum amounts to mm. Low native soil phosphorus (P) availability coupled with poor utilization efficiency of added P is a major constraint limiting the productivity of soybean–wheat system on Vertisols in Phosphorus in Indian vertisols book semi-arid tropics.
In India, three main reasons which call for immediate need to improve the use efficiency of fertiliser phosphorus (P) are: i) rock phosphate being a non renewable resource is becoming scarce, ii.

In Sudanese Vertisols, montmorillonite accounts for over. 90% of the clay fraction (Jewitt et al. In Indian as well as in Ethiopian Vertisols, montmorillonite is the dominant clay mineral (Khanna ; De Vos and Virgo ; Chatterjee and Rathore ).
Limited data on Australian soils indicate that soils regarded as Vertisols contain. 1. Introduction. Phosphorus (P) deficiency is one of the major nutritional constraints to crop production on Indian Vertisols (Murthy, ; Bansal and Sekhon, ).Coupled with low native soil P availability is the problem of poor utilization efficiency of applied fertilizer P because of its transformation into relatively less available forms in soils.
A Vertisol, or Vertosol, is a soil type in which there is a high content of expansive clay minerals, many of them known as montmorillonite, that form deep cracks in drier seasons or a phenomenon known as argillipedoturbation, alternate shrinking and swelling causes self-ploughing, where the soil material consistently mixes itself, causing some Vertisols to have an extremely deep A.

Soybean followed by wheat is an important double cropping system on Vertisols in the semi-arid tropical (SAT) region of India.
The average productivity of soybean ( Mg ha −1) and wheat ( Mg ha −1) in this cropping system is very small, however, owing mainly to low phosphorus (P) fertility status (Tandon, ; Katyal and Das, ; Subba Rao and. In conclusion the results of our study show that the Vertisols studied have low phosphate adsorption capacity and that the P they adsorbed is easily desorbable.

Nitrogen and phosphorus are often cited as the most limiting nutrients in agricultural soils of Ethiopia. Their availability in the soil solution also determines the growth and productivity of the soils and crops.
Thus, experiments were conducted to investigate the response of upland rice and determine the optimum rates of N and P fertilizers. Naturally, P is an immobile element in the soil compared to N and other nutrients. Moreover, its availability to plants is pH dependent, and has a limited pH range to be available, mostly between.Phosphorus in hindi, फॉस्फोरस का उपयोग पोषक तत्वों की कमी (Nutritional Deficiencies) आदि के लिए किया जाता है। जानें Phosphorus का उपयोग, दुष्प्रभाव, संरचना, विकल्प, इंटरैक्शन, सावधानी.Journal of the Indian Society of Soil Science Year:Volume: 51, Issue: 3 First page: () Last page: () Print ISSN: X.
