Recover to white clover K because of effect oflime, When lime and P fertilization were applied 6330 kg/hm2 and 1530kg/hm2, acquire perfect flowernumbers of wliite clover being interrelate dry matter.
As a result, the quantity of fixed K increased, the PBC~k and Ke increased, △G decreased, the recovering of white Clover K strengthened. When Lime and P fertilization were applied with 6330 kg/ha and 1530 kg/ha, perfect number of White Clover flower related to dry matter was obtained.
This study assessed the effect of eight lime application rates, with four field replications, on the activities of 14 enzymes involved in C, N, P, and S cycling in soils.
The difference of specific surface, zero point of charge, zero point of net charge and phosphate adsorption in reddish soils and yellow brown soil is related to their clay mineral association.Exchangeable AI in reddish soil is a major factor leading to soil acidity.The strong replacing power of Al will enhance the leaching loss of nutrient cations and lead to an aggravated delpetion of nutrient. Plant growth problems associated with poor root penetration into acid subsoils are frequently associated with hig...
Ten types of soil were collected from Guangdong Province in South China and planted to Graham stylo (Stylosanthes guianensiss cv. Graham) in pots so that nutrient requirements could be assessed. The main results of the experiment are as follows: The response of the stylo to P fertilizer in many soils was good, but P fertilizer had no significant effect on stylo in the soil where available P was higher than 5 ppm. or available P was ranging from 3 to 5 ppm and the soil pH was greater than 7. Liming on high p...
The study was conducted on testing in acidic soil with lime in Guizhou Herbage Seed Multiplying Farm. This paper analysis the relationship of supplying K in soil by nutrient availability energy. Lime contribute to the fixing of K in acidic soil. As a result, the quantity of fixed K increased, the PBC~k and Ke increased, △G decreased, the recovering of white Clover K strengthened. When Lime and P fertilization were applied with 6330 kg/ha and 1530 kg/ha, perfect number of White Clover flower related to dry m...
