Abstract

Inceptisol soils mainly have medium to high physical properties. However, these physical properties can be degraded if there is a limiting factor in the terrain, which is the degree of slope and low SOC. On steep slopes, soil infiltration rates decrease, which leads to the limited available soil moisture in root zone subsoil. Application of compost or manure into the soil can improve soil physical properties and increase the soil organic carbon (SOC), it improves soil porosity and improve available water capacity (AWC).  This study used the factorial completely randomized design with 8 treatments and 4 replications. The treatments included (Control + Topsoil), (Control + Subsoil), (Compost + Topsoil), (Compost + Subsoil), (Cow manure + Topsoil), (Cow manure + Subsoil), (Goat manure + Topsoil), (Goat manure + Subsoil). The results showed that (1) the addition of compost and manure can improve the physical properties of topsoil and subsoil, reducing macro porosity, increasing meso and microporosity, and increasing field capacity. (2) The addition of compost and manure can increase the water holding capacity of topsoil by 36.72% at 1 MAI to 41.12% at 5 MAI and inceptisol subsoil by 35.27% at 1 MAI to 36.42% at 5 MAI. (3) The addition of compost and manure can increase the C-organic content of topsoil by 1.62% at 1 MAI to 1.72% at 5 MAI and subsoil by 1.24% at 1 MAI to 1.38% at 5 MAI.

Abstract

Smallholder coffee plantations cover a very large area on inceptisol soil with low productivity; so far, the provision of organic materials in coffee plantations is done by placing it on the surface of the soil so that it is susceptible to loss due to runoff and erosion. This study was conducted by mixing organic materials with topsoil and subsoil to determine their effect on the characteristics of topsoil and subsoil. This study used a Completely Randomized Design (CRD) with 8 treatments and 4 replications. The experimental treatments consisted of P1 (topsoil), P2 (subsoil), P3 (topsoil + Compost); P4 (subsoil + compost); P5 (topsoil + cow manure); P6 (subsoil + cow manure); P7 (topsoil + goat manure); P8 (subsoil + goat manure). The soil was incubated at field capacity conditions for 16 weeks. Soil parameters include: soil pH, soil CEC; soil organic C levels; Ca exchange, Mg exchange, K exchange, and Na exchange. The dose of organic material (cow and goat manure) is 30 tons. ha-1. Providing compost and manure can increase inceptisol soil fertility at the depth of the topsoil and bottom soil (exchangeable K, exchangeable Ca, exchangeable Mg, soil pH, Organic C, and soil CEC levels), this increase is significant compared to the control.
