Question

Which factor are affecting in agriculture organic fertilizer in india?

Answer 1

The pH value of soil,the amount of calcium carbonate in soil

Answer 2

Sub-Saharan Africa faces huge food

supply challenges due to increasing human pop-

ulation, limited opportunities to increase arable

land, and declining yields associated with contin-

uously declining soil fertility. To cater for their

food requirements, smallholders use only modest

levels of inorganic fertilizers and rely to a large

extent on manure, which is generally of low

quality. To explore factors influencing fertilizer

and manure use at the farm level, 253 farm

households in Vihiga district of western Kenya

were sampled. A pair of Tobit models was used to

relate amounts of manure and fertilizer used to

household variables. The results indicate that the

use of both manure and fertilizer reciprocally

influence each other and are strongly influenced

by household factors, and also imply that manure

and fertilizer uses are endogenous. Policy changes

are required to (1) reduce the burden on farming

alone in rural areas; (2) promote the use of

higher-cost, higher-value inputs such as fertilizers;

(3) improve access to input and output markets;

and (4) encourage farmer education so as to

promote sustainable soil fertility management.

Improved understanding of the biophysical and

socioeconomic environment of smallholder sys-

tems can help target sustainable soil fertility

interventions more appropriately.
