Abstract

Forest conversion for plantation and the continuous fertilizer usage without organic materials has potentials to produce soil damage with the soil compaction. One of efforts to improve sustainable land productivity is by applying organic materials. The use of organic materials of vermicompost, fruit peel fertilizer, and cow manure in long term is expected to be able to improve the physical properties of soil at the robusta coffee plantation (Coffea canephora  Pierre). The research was conducted at robusta coffee plantation of PT Perkebunan Nusantara XII (Persero), Bangelan Village, Wonosari District, Malang Regency. The research used factorial random design of nested pattern with 2 factors: (1) organic material treatment (control, vermicompost, coffee fruit peel fertilizer, and cow manure),  (2) the soil depth level (0-10 cm, 10-20 cm, and 20-30 cm. The results showed that application of vermicompos improved higher organic matter than the application of coffee peel fertilizer, cow manure in depth of 0-10 cm. The application of various organic materials did not improve the organic materials of soil in depth of 10-20 and 20-30 cm. The application of vermicompost, coffee peel fertilizer and cow manure improved aggregate stability than without the application of organic material (NPK). Organic materials had a positive relation with soil aggregate stability in depth of 0-10 cm (r = 61%), so the higher organic material content, the higher soil aggregate stability, while in depth of 10-20 cm and 20-30 cm there was no significant relationship

Abstract

The water content of the soil in Jatikerto is 32,02%. As it is supported by clayey loam soil texture, the soil is able to absorb more water, but the water in the soil cannot necessarily be available to the plants. One effort to maintain the availability of ground water can be done with the soil amendments materials such as biochar. This study used three types of biochar, i.e. rice husk, coconut shell, and wood with each contained three doses (15, 30 and 45 t ha-1). This study used ten treatments with two factors consisted of types and doses of biochar. Soil sampling was conducted at 2 points on the array and on an array, and each point was conducted on soil depth of 0-20 cm and 20-40 cm. The variables measured were soil texture, soil bulk density, soil porosity, pore space distribution, pore fast drainage, pore slow drainage and pores water available. The results indicated that treatments of types and doses of biochar did not change the texture of the soil. The highest soil bulk density contained in biochar types of wood biochar dose of 30 t ha-1 (1,20 g cm-3), while for soil particle density was not significantly influenced by the biochar treatments. The average value of the highest porosity was measured on the type of wood biochar dose 15 t ha-1 (47,54% vol). The highest pore fast drainage contained in biochar types of coconut shell biochar dose of 30 t ha-1 (20,80% vol), while for the highest available pore water was on the type of coconut shell biochar dose 45 t ha-1(21,55% vol). The highest pore slow drainage was on the type of wood biochar dose 30 t ha-1 (29,03% vol).

Abstract

Organic matter application can improve to soil structure. The purpose of this study was to explore  the effects of application of various organic matters (cow manure, vermicompost and coffee fruit skin) to soil total porosity in plantation-based robusta coffee (PTPN XII) Bangelan , Wonosari, Malang. The study was conducted using a factorial randomized block design and nested design pattern with the first factor was the type of fertilizer treatment (type of organic matterr), i.e. P1 (plot applied with vermicompost), P2 (plot applied with rind coffee), P3 (plot applied with cow manure), and P4 (plot applied with NPK / control). The second factor was the depth of soil, i.e. K1 (0-10 cm depth), K2 (10-20 cm depth), and K3 (20-30 cm depth). Parameters observed were soil texture, soil bulk density, soil bulk density, soil porosity, soil organic C, and soil pH. The results showed that application of organic materialss (cow manure and vermicompost) was able to improve total porosity of the soil. C-organic content of the soil was  highest at the plot applied with vermicompost.
