Phosphorus Adsorption

One of the approaches for phosphorus fertilizer management is controlling the soil phosphorus adsorption behavior. To examine the effect on phosphorus adsorption behavior, three amended soil samples were prepared by mixing 10% (w/w in dry basis) cow dung, biogas slurry and vermicompost with soil. Phosphorus adsorption behavior was examined by using Langmuir, and Temkin adsorption isotherms. Initially, biogas slurry and vermicompost increased the maximum phosphorus adsorption capacity (MPAC) of soil from 461 µg g-1 (control) to 558.0357 and 586.17 µg g-1 respectively, and then decreased steadily and reached 429.92 and 398.41 µg g-1 respectively in five weeks.  Whereas in case of cow dung, MPAC was initially decreased, then reached maximum in 17 days and ultimately decreased. Thus application of cow dung along with phosphate fertilizer seems to increase the loss of the fertilizer through runoff and leaching. Conversely, biogas slurry and vermicompost prevent phosphorus loss by regulating phosphorus release through initial enhancement followed by gradual decrease in phosphorus adsorption capacity of soil. Both biogas slurry and vermicompost can be considered as good soil amendments as they have the ability to control the release of phosphorus fertilizer as per the need of the plants.

Phosphorus (P) sorption by soils is a phenomenon that varies depending on soil characteristics, influencing its intensity and magnitude, which makes it a source or drain of P. The objective of this study was to determine the Maximum Phosphorus Adsorption Capacity (MPAC) and desorption of P from soils under native Savanna Brazilian and verify the correlation between MPAC and P Capacity Factor (PCF) with the chemical and physical properties of these soils. The study was conducted in seven soils under native Savannas. The Langmuir isotherms were adjusted from the values obtained in sorption assays, being evaluated the MPAC, the energy adsorption (EA) and PCF, which was calculated according to the levels of P-adsorbed and P-sorbed. Values of MPAC were classified as high in most soils, ranging from 283 up to 2635 mg kg-1 of P in the soil and were correlated with soil organic matter, clay, silt, sand, base saturation and pH. The PCF was higher in soils where the MPAC was also higher. The use of only one attribute of soil (clay content) as a criterion for the recommendation of phosphated fertilization, as routinely done, is susceptible to errors, needing the use of more attributes for a more accurate recommendation, as a function of the complexity of the interactions involved in the process.

SUMMARYField studies were made for 2 years on a sandy loam soil under dryland conditions of north-west India with three pigeon-pea varieties in relation to plant density and the application of phosphate fertilizer. Varieties Pusa Ageti and P4785 with better developed root system and profuse nodulation had higher grain and stalk yield, and higher N and P yield than Prabhat. Root and shoot growth and root nodulation were adversely affected with increasing plant densities in the range 50 × 103 and 150 × 103 plants/ha. Stalk and total N and P yield increased with increasing plant density. Plant density of 117 × 103 plants/ha produced maximum grain yield of 1·53 t/ha. Phosphorus fertilizer promoted root and shoot growth, intensity and volume of nodulation and increased grain, stalk, N and P yield. The effect of plant density on grain yield was more pronounced in the presence of phosphate fertilizer. The economic optimum rate of P ranged between 22·1 and 23·1 kg/ha under different plant densities.

The Way

In a pot-type experiment with ryegrass, 32P was used to label isotopically exchangeable soil phosphorus as well as a phosphate fertilizer. The tagging of both forms of phosphorus enable us to determine the pool (L) for soil reserves and the A value which is the availability of these reserves in the presence of fertilizer. The authors establish correlations between the ratio K = L/A and the assimilable phosphorus as determined by the Bray II method, and also between K and the "extra" phosphorus. The authors state that the latter was the difference between the plant phosphorus with and without fertilizer. From this study it is concluded: (1) that the K value seems to be a better criterion than the amount of assimilable phosphorus to estimate the phosphorus fertility of a soil; (2) that the study of the variation of the K value according to the soil types informs us about the reserves behavior and about the way of nutrition for the plant. The calculation of the K value is aimed toward a more adequate fertilization for given types of soil.

Pasture Yield

The level of soil phosphorus and the response of irrigated perennial pasture to phosphorus fertilizer were measured on 33 sites in the Goulburn Valley of northern Victoria. Eleven of the 33 sites were found to have Olsen P values above 10 p.p.m. and Colwell P values above 30 p.p.m. Of these 11, 9 did not give a pasture response to superphosphate and 2 gave a relatively small response. Functions of the form Y = a - be-CX (where Y = total pasture yield over 12 months (t ha-1), X = rate of superphosphate application (t ha-1), and a, b and c are constants respectively denoting maximum yield, maximum response, and the rate at which maximum yield is approached) were fitted to the yield data from those sites at which a response did occur. b was found to be correlated with a number of soil tests, the highest correlation coefficient being -0.74 for Colwell P. a was significantly correlated with some tests (P < 0.01) but was generally less predictable, and c gave very low correlation coefficients with all soil tests.

Fertilizer experiments indicated that much higher plant response to phosphorus occurred on moderately saline than on non-saline soil. Soil analyses showed that this difference could not be explained by the amount of sodium bicarbonate extractable phosphorus contained in these two soils.Greenhouse experiments with artificially salinized soil indicated that the uptake of phosphorus by barley plants was related to the salt concentration in the soil. Phosphorus absorption increased with increasing salt concentration, reached a maximum when the saturation soil extract measured approximately 6 millimhos, and then declined with further increases in salt concentration. This relationship was similar for fertilized and unfertilized plants. However, the increase in phosphorus absorption was much greater when phosphorus fertilizer was applied.The same relationship between salt concentration and phosphorus absorption was obtained with increasing NaCl concentration in liquid cultures. Maximum phosphorus absorption by barley occurred when the solution contained between 0.05 and 0.10 molar NaCl This relationship is attributed to the effect of salts on the physiology of the plant rather than the effect of salts on phosphorus solubility.
