Status Kesuburan Tanah Sawah Pasang Surut di Desa Pasir Kecamatan Mempawah Hilir Kabupaten Mempawah

This study aims to determine and study the soil fertility status of Tidal Paddy soil based on the type of overflow as a consideration in land management and provide fertilizer suggestions for tidal paddy soil in Pasir Village. This research method is a soil survey with sampling at a depth of 0-20 cm with a grid system, the samples taken are located in the three types of paddy soil, namely types A, B, and C overflow and analyzed in the laboratory. Soil parameters measured were soil pH, C-organic, N-total, P-total, K-dd, K2O Mg-dd, KTK, KB. The results showed that the soil fertility of the paddy soil in the overflow types A, B, and C have has low criteria. The soil fertility is classified as low due to the low KTK, KB, P-total and C-organic values of the soil. Efforts to fulfill the nutrients found in the land are given fertilization suggestions as follows: in the paddy soil of overflow type A 282.60 kg / ha urea, SP-36 at a dose of 112.41 kg / ha and KCL at a dose of 292.15 kg / Ha. In the paddy soil of overflow type B, 271.73 kg / Ha of urea, SP-36 at a dose of 115.02 kg / Ha and KCL at a dose of 334.75 kg / Ha. Overflow type C paddy soil with a dose of 280.43 kg / Ha of urea SP-36 at a dose of 58.63 Kg / Ha and KCL is recommended to provide a of 254.49 kg / Ha.
