Deskripsi
Systematic studies were undertaken in the intra zeolitic media to better understand the ability of zeolite type LTA in occluded nitrogen used in fertilizer and soil conditioning. We have measured the dry matter production from the cultivation of corn in a greenhouse for about 40 days, and also the amounts of nitrogen absorbed, retained and lost by leaching. The dry matter production in the cultivation with different concentrations of nitrogen occluded in the zeolite, was more efficient than the traditional fertilizer, which demonstrated better use of nitrogen to reduce leaching losses, which implies a possible reduction of costs for nitrogen.
