Mechanism in Using Commercial High Efficient Zeolite-Base Greenfeed Slow Release Fertilizers

Abstract

Fertilizer issues such as overuse, leaching and soil degradation are becoming severe in worldwide plantation areas. To secure current food production, prevention measures on these issues are relatively limited on agricultural production areas. Slow release fertilizer is prevailing over past years due to its significant effects on prevention of fertilizer leaching and less harm to soil and underground water. We presented here the mechanisms of a novel zeolite-based slow release fertilizer including its properties as reservoirs of nutrients, pH balancer and also water retainer in soil. By providing sufficient nutrients to soil, this fertilizer has commercially proven to give better growing environment to grower as well as labor saving and cost saving.

Preparation and Characterization of Attapulgite‐Fly Ash–Based Binuclear Slow‐Release Fertilizer Encapsulated by Eudragit

“…The EC was increased by the release of urea fertilizer, but other soil factors had a synergistic effect. For example, absorption of NH 4 + was a proton generating process and led to a decrease in the external pH (Wea et al, 2018). Different from the linear relationship between relative pH, EC, and N leaching rate in water, it was closer to the exponential relation in the soil column.…”

Pengaruh Pemberian Zeolit Alam Teraktivasi terhadap Sifat Kimia Tanah Podsolik

“…Zeolit merupakan mineral kristal aluminasilikat yang terdiri dari ion Na + , K + , Ca + , Mg + yang membentuk kerangka tiga dimensi dari atom Si dan atom Al yang saling berhubungan (Khodanazary, 2013). Penerapan zeolit sebagai bahan amelioran mampu memperbaiki sifat kimia tanah didasarkan atas kemampuannya melakukan pertukaran ion, adsorpsi, penyerap molekul, meningkatkan efisiensi pemupukan, meningkatkan KTK tanah dan ketersediaan ion Ca, K, dan P, serta mampu menurunkan kandungan aluminium (Vidal, 2009;Jakkula, 2018;Tan, 2018). Sifat fisik dan kimia yang dimiliki zeolit yakni struktur berongga, berisi ion-ion logam yang dikelilingi molekul air bebas bergerak dan adanya distribusi ion Si 4+ oleh Al 3+ pada pembentukan zeolit.…”
