Book Synopsis Phosphorus Requirements in Soils Amended with Organic Materials by : Ronaldo Severiano Berton
Download or read book Phosphorus Requirements in Soils Amended with Organic Materials written by Ronaldo Severiano Berton and published by . This book was released on 1987 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: The addition of organic residues to the soil may modify the amounts of plant available phosphorus (P) found in this ssytem. These studies were undertaken to evaluate the suitability of the sorption isotherm technique for estimating the amounts of inorganic P required for optimum plant growth, the correlation of P availability with the amount of P extracted by three chemical methods, and with the activity of two phosphatase enzymes, when soils were amended with organic materials. Acid phosphatase and phosphodiesterase activities were also compared with the P availability to plants. Soil phosphodiesterase activity correlated better with corn yield and plant uptake than acid phosphatase activity. The correlation of phosphodiesterase activity with microbial activity might be used to indicate the contribution of the soil organic P pool in the P supply to the plant.

This book was released on 1979 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: In three soil from southern Bahia(Brazil) a local (Patos) rock phosphorus wa compared with monocalcium phosphate and Gafsa and Morocco rock phosphates as a source of P by sorghum and by phosphate soil parameters. The utilization of Patos rock phosphate by two legumes and two grasses with VA mycorrhizal infection and NH4 or NO3 nitrogen nutrition was evaluated and, using soil blocks, pH gradients at different distances from the root plane were determined. Low fertilizer value was recorded for Patos rock phosphate, the effectiness of whic increased with storage time only in a clay soil having high organic matter content, CEC, and high adsorption capacity. In all soils Gafsa and Morocco showed equal or higher effectiveness than monocalcium phosphate. The low availability of Patos in related to its mineralogical composition, to low solubility in 2% citric acid and low amounts of phosphate extracted by anion exchange resin. The highest rate of P immobilization was recorded in a soil having a high content of Al and Fe extracted by dithionite and pyrophosphate, and also goethite and gibbsite as revealed by X-ray examination. The behaviour was note realed by x-ray examination. This behaviour was note related to the amounts of Al and Fe extracted by oxalate, exchangeable e Al or to the adsorption-dsorption properties using o,01M CaCl2 solutions. Phosphate extracted by anion exchange resin showed the best correlation with P uptake by sorghum, E value P soluble in water being second and third best. Poor correlations ...
