The ash produce due to biomass burning in jhum increases the
A)
P
B)
N
C)
Cu
D)
Allofthese
In the context of Jhum (shifting cultivation) practiced in Mizoram and other hilly regions, biomass burning converts organic matter into ash. During combustion, volatile elements like Nitrogen (N) and Sulfur (S) are largely volatilized and lost to the atmosphere as gases (e.g., NO2, N2O). However, non-volatile minerals and elements such as Phosphorus (P), Potassium (K), Calcium (Ca), and Magnesium (Mg) are concentrated in the remaining ash. Therefore, the ash produced significantly increases the available Phosphorus (P) in the topsoil, providing a temporary nutrient boost for the crops. Nitrogen (N) actually decreases due to volatilization, and while trace elements like Copper (Cu) may be present, the primary and most significant nutrient increase associated with ash in soil science textbooks regarding slash-and-burn agriculture is Phosphorus.
