Peningkatan Kesuburan Tanah Dan Hasil Padi Sawah Melalui Aplikasi Pupuk Organik

Abstract

The yield of irrigated paddy rice in Sri Agung Village has decreased. In the last four years, the increase in the addition of input units (fertilizers) has not been followed by an increase in economic yields. This study aims to analyze the effect of organic fertilizers on soil fertility, such as pH, total N, organic C, available P and available K. The research was conducted in the rice fields of Sri Agung Village. Batang Asam area, West Tanjung Jabung Regency - Jambi. The research was conducted from April to September 2020. The study used a randomized block design with six treatments and five replications. The treatments tried were: Recommended Fertilizer (R), five types of organic fertilizer with a dose of 10 t ha-1 each, namely, Petroganik+R ( P1), Compost Solid Decanter + R (P2), Chicken Manure + R (P3 ), Cow Manure +R (P4) and Industrial Waste Compost + R (P5). The results showed that organic fertilizers significantly increased available K content of paddy soil but they did not significantly increase soil pH, total N, organic C and available P. The highest yield of dry milled grain (7.52 t ha-1) was obtained at +R (P1) Petroganic treatment.

Analysis of soil fertility status on rice (Oryza sativa L.) planted land in Polewali District, Polewali Mandar Regency

“…One effort to increase rice productivity is by fertilizing. Fertilizing using inorganic fertilizers such as Urea and TSP provides nutrients to plants relatively quickly, but has the potential to reduce the soil pH to a lower level which will affect the availability of other nutrients for plants (Mahbub et al, 2023). The data in Table 2 shows that the soil pH tends to decrease so that it is slightly acidic.…”

“…Using organic fertilizer can minimize land damage caused by excessive use of inorganic fertilizer. Mahbub et al (2023) states that the role of organic materials is as a supplier of nutrients and improving soil properties which can maintain the availability of nutrients in the soil. Organic fertilizer can come from plant remains or animal waste.…”
