Although total nutrient application rates were much lower for CRF, our results suggest that on tropical restoration sites, CRF may promote seedling performance at least equally to that of IAF.
The rate of nutrient application (milligrams of element per kilogram of soil sand mixture: N 40, P 50, K 100, Ca 101, Mg 28, S 20, Zn 2.0, Cu 2.0, B 0.1, Mo 0.1) represented the recommended fertility level for crop-pasture establishment (Rao et al. 1992).
This preliminary study demonstrates that by proper management of the pH and optimization of application rate, MSGW can be utilized as a nutrient source for plant growth.
Results from the current study demonstrate that the loss of N in N2O emissions from wetland soil subjected to cattle manure applications constitutes an important nutrient flux, and the magnitude of the losses depended upon application rate and content of N (manure quality) in applied manure.
However, at the fourth soil sampling (after harvesting mustard 3), the soil nutrients in the plots treated with vermicompost V3 at an application rate of 20 t ha−1 were higher than the other treatments.
Increase in N application rate increased TE at the vegetative phase for fast nutrient releasing fertilisers (DFS, ECO, EC, NPK + (NH4 2SO4, (NH4 2SO4) and at the reproductive phase for slow nutrient releasing fertilisers (C and CO).
Today, in Estonia, the weekly e-residency application rate exceeds the birth rate.
However, nutrient availability from chemical fertilizers is not more than 20% and has forced the poor farmers to add two times more than the optimum application rate of P-fertilizers.
Nutrient application to any plant results in higher nutrient content in their tissues by enhancing nutrient uptake through their roots (Rashid et al. 2016a).
It is recommended that application rate of 20 t ha−1 for cattle, 40 t ha−1 for goat and poultry manure at the rate of 10 t ha−1 would provide optimum and improve the soil nutrients level which will be retained in the soil for longer period.
