BEBERAPA SIFAT KIMIA TANAH PASCAPANEN TANAMAN KEDELAI (Glycine max L.) SETELAH DIPUPUK NPK DAN KAPUR PADA LAHAN PASANG SURUT

- Soybean is one of the important food crops after rice and corn. Fertilizer is one of the most important factors to get high crop yields and maintain soil fertility. The presence of fertilizer residues can be planted by subsequent crops, so there is no need for additional fertilizer. Writing this field research aims to examine the effect of NPK fertilizer and lime fertilizer on some chemical properties of postharvest soil in tidal land. This field research has been carried out in Mulia Sari Village, Tanjung Lago District, Banyuasin Regency, South Sumatra Province. From September to December 2018. Using a factorial randomized block design consisting of two factors and three replications. The first factor is the dose of lime (K), the second factor is the dose of fertilizer (P). The results showed that from the results of soil analysis P residues occurred because the P content was still high. Giving location specific fertilizer dosage and fertilizer recommendation for south sumatra agricultural balibang and lime dose equivalent (0,25xAl-dd), (0,50xAl-dd), (0,75xAl-dd) not significant effect on some soil chemical properties such as pH, C-Organic, N-Total, P-Available, K-dd, KTK, Ca, Mg and Al-dd.
