effect of solar radiation on soil nutrients pdf
The effect of total solar. radiation on nutrient concentration (mean values for 11 chrysanthemum cultivars) is. summarized in Figs 2â9. The increase of radiation (in MJ m-2) caused decreased. concentration of nitrogen, phosphorus, potassium, calcium, magnesium, cuprum and. boron in chrysanthemum leaves.
Solarization affects all living organisms that are present in the upper 30 cm (11.8 in) of the soil. It can be used to manage weeds, diseases caused by soil-borne pathogens, and nematodes. Effectiveness of solarization can be somewhat variable when methyl bromide is the standard with which it is compared.
