Someone explain both for me please.

answer 1 :
so the crop can grow more healthier.

answer 2 :
if the equation can be reversed :
increase in temp will shift the equilibrium to the endothermic side (vise versa)
increase in pressure will shift the equilibrium to the low mole side (vise versa)
increase in concentration of the reactant will shift the equilibrium to the right side (vise versa)
