Abstract

Agriculture land shows soil compaction problems due to long-term agricultural cultivation activities. Soil compaction indicator can be seen from the value of soil penetration resistance at different soil depths (0 - 60 cm). This research aimed to determine soil penetration resistance at different coffee plantation ages with different soil depths and to analyze the relationship between soil penetration resistance with soil physical characteristics and coffee productivity. The survey activities include observation of minipits, measuring soil penetration resistance at soil depths of 0-20 cm, 20-40 cm, and 40-60 cm using a hand penetrometer, and soil sampling. The results showed that the soil penetration resistance at each LU and soil depth suggested variation were categorized into moderate and high soil penetration resistance classes (1.34 MPa - 3.35 MPa). Soil characteristics, such as soil aggregate stability, water content, bulk density, porosity, silt content, and clay content, significantly correlate with soil penetration resistance. However, soil penetration resistance has a negative correlation with coffee productivity. The value of soil penetration resistance (at a depth of 0-60 cm) has a significant negative correlation with the average productivity of coffee plantations (r=-0.5936**). Therefore, increased soil penetration resistance decreased root growth, decreasing plant productivity.

Abstract

Kualitas tanah dasar merupakan salah satu indikator keberhasilan pertumbuhan dan produksi tanaman kopi. Salah satu faktor pendukung kualitas tanah adalah sifat fisik tanah, terutama pada stabilitas agregat tanah. Tujuan dari penelitian ini adalah untuk menganalisis tingkat stabilitas agregat tanah dan hubungan antara stabilitas agregat tanah dengan sifat fisik tanah dasar lainnya serta terhadap produktivitas tanaman kopi. Penelitian ini menggunakan metode survei lapangan dengan metode purposive soil sampling. Analisis stabilitas agregat tanah menggunakan metode wet sieving. Parameter dalam penelitian ini adalah stabilitas agregat tanah, porositas tanah, berat jenis, berat jenis, dan tekstur tanah berupa fraksi pasir, lanau dan liat. Hasil penelitian menunjukkan bahwa stabilitas agregat tanah pada beberapa kelas umur tanam kopi dan kedalaman tanah yang berbeda memiliki nilai stabilitas agregat tanah yang berbeda, tetapi semuanya tergolong "Sangat stabil". Stabilitas agregat tanah memiliki hubungan yang signifikan dengan beberapa sifat fisik tanah lainnya seperti bulk density, porositas, fraksi liat dan fraksi lanau. Selain itu, stabilitas agregat tanah memiliki pengaruh yang signifikan terhadap produktivitas tanaman kopi.

Abstract

Subsoil compaction indicator can be seen from the value of soil penetration resistance (SPR). Information related to the distribution of soil penetration resistance is important as the efforts to increase coffee production due to the relation to development of coffee roots, while at the research location does not have yet this information. Therefore, further research is needed to know the soil penetration resistance at several coffee ages with different soil depths and to analyze the relation between soil penetration resistance with other soil physical properties, coffee growth, as well as productivity of coffee crops in the Robusta coffee plantation. This research activity was carried out by survey method and purposive sampling method. The survey activities include making minipits, measuring soil penetration resistance at coffee plantation with a coffee plant age of 5 to >20 years at a soil depth of 0-20 cm, 20-40 cm, and 40-60 cm by using a hand penetrometer, taking soil samples, and measuring coffee plant growth. The results showed that soil penetration resistance (SPR) in smallholber coffee plantations in the coffee root zone is classified into the “Medium” and “High” soil penetration resistance classes (1.34 MPa to 3.35 MPa). Variations in SPR values are caused by differences of cpffee age, agricultural activities in coffee plantations, and soil physical characteristics. Several physical properties of the soil that are closely related to the soil penetration resistance value are aggregate stability, water content, bulk density, porosity, silt content, and clay content. The soil penetration resistance value is closely related to the productivity of Robusta coffee, with a correlation coefficient value of -0.5936**.
