Latifah, Hanif and Prof. Dr. Ir. Soemarno, MS (2023) Pengaruh Pemberian Kapur Pertanian dan Pupuk Kandang Kambing terhadap N, P dan C Organik Tanah Berpasir Desa Bambang Kecamatan Wajak. Sarjana thesis, Universitas Brawijaya.
Abstract
Kesuburan tanah berkaitan dengan penyediaan unsur hara di dalam tanah. Tanah yang mempunyai kesuburan yang baik mampu mendukung pertumbuhan dan perkembangan tanaman. Kesuburan tanah dapat diketahui melalui karakteristik tanah, baik dari sifat fisik, kimia dan biologi tanah. Tanah di Desa Bambang mempunyai tekstur dominan pasir. Tanah dengan fraksi dominan pasir mempunyai kesulitan dalam menahan air dan menyimpan unsur hara. Adanya unsur hara yang rendah menyebabkan kesuburan tanah rendah sehingga akan berdampak terhadap pertumbuhan tanaman. Adanya beberapa keterbatasan pada tanah maka perlu dilakukan perbaikan dengan penambahan kapur pertanian dan bahan organik. Pemberian kapur pertanian berupa CaCO3 dan bahan organik berupa pupuk kandang kambing diharapkan mampu memperbaiki sifat kimia tanah terutama Ntotal, P-tersedia, C-organik pada tanah berpasir. Kegiatan inkubasi dilakukan pada bulan Juni hingga Desember 2022 yang dilaksanakan di greenhouse Fakultas Pertanian Universitas Brawijaya. Penelitian menggunakan Rancangan Acak Lengkap Faktorial dengan 3 faktor yaitu faktor kedalaman tanah (0-30 cm dan 30-60 cm), dosis kapur kalsit (0 ton/ha, 3 ton/ha) dan dosis pupuk kandang kambing ( 0 ton/ha, 20 ton/ha dan 40 ton/ha) dengan ulangan sebanyak 3 kali sehingga terdapat 36 pot perlakuan. Parameter yang dianalisis yaitu pH H2O, pH KCl, N-total, P-tersedia, C-Organik dan Ca-dd. Hasil analisis yang didapatkan kemudian diolah menggunakan analisis anova taraf 5% dan dilakukan uji lanjut Duncan Multiple Range Test (DMRT) taraf 5% untuk mendapatkan perlakuan terbaik menggunakan aplikasi SPSS. Kemudian dilanjutkan dengan analisis korelasi dan regresi berganda untuk mengetahui hubungan antar parameter yang diamati. Hasil penelitian menunjukkan bahwa pemberian pupuk kandang kambing dan kapur pertanian pada dua kedalaman (0-30 cm dan 30-60 cm) meningkatkan nilai pH H2O, pH KCl, N-total,P-tersedia, C-organik dan Ca-dd. Aplikasi dosis pupuk kandang 40 ton/ha dan dosis kapur pertanian 3 ton/ha meningkatkan pH H2O, pH KCl, P-tersedia, dan Ca-dd. Sedangkan pemberian pupuk kandang kambing 40 ton/ha meningkatkan terhadap N-total dan C-organik. Hasil analisis menunjukkan parameter pH H2O, pH KCl dan Ca-dd berkorelasi sangat kuat terhadap P-tersedia dan berpengaruh sebesar 70% pada kedalaman 0-30 cm, sedangkan pada kedalaman 30-60 cm parameter pH H2O, pH KCl,Ca-dd berkorelasi sangat kuat dan BOT berkorelasi kuat terhadap P-tersedia dan berpengaruh sebesar 67%. Pada parameter N-total, BOT dan C/N berkorelasi sangat kuat. BOT dan C/N berpengaruh terhadap kandungan N-total sebesar 99.4% pada kedalaman 0-30 cm dan sebesar 99.5% pada kedalaman 30-60 cm.
English Abstract
Soil fertility is related to the provision of nutrients in the soil. Soil that has good fertility can support plant growth and development. Soil fertility can be determined through soil characteristics, both from physical, chemical, and biological soil properties. The soil in Bambang Village has a dominant sand texture. Soil with a dominant fraction of sand has difficulty retaining water and storing nutrients. The presence of low nutrients causes low soil fertility which will have an impact on plant growth. Despite the existence of several limitations on the soil, it is necessary to improve it with the addition of agricultural lime and organic materials. The provision of agricultural lime in the form of CaCO3 and organic materials in the form of goat manure is expected to improve soil chemical properties, especially N-total, P-available, and C-organic in sandy soil. Incubation activities were carried out from June to December 2022 in the greenhouse of the Faculty of Agriculture, Universitas Brawijaya. The study used a factorial complete randomized design with 3 factors: soil depth (0-30 cm and 30- 60 cm), calcite lime dose (0 tonnes/ha, 3 tonnes/ha), and goat manure dose (0 tonnes/ha, 20 tonnes/ha, and 40 tonnes/ha) with 3 replications so that there were 36 treatment pots. The parameters analyzed were pH H2O, pH KCl, N-total, Pavailable, C-Organic, and Ca-dd. The analysis results obtained were then processed using ANOVA analysis at the 5% level and further Duncan Multiple Range Test (DMRT) at the 5% level to get the best treatment using the SPSS application. Then continued with correlation analysis and multiple regression to determine the relationship between the parameters observed. The results showed that the application of goat manure and agricultural lime at both depths (0-30 cm and 30-60 cm) increased the values of pH H2O, pH KCl, N-total, P-available, C-organic, and Ca-dd. Application of 40 tonnes/ha manure dose and 3 tonnes/ha agricultural lime dose increased pH H2O, pH KCl, P-available, and Ca-dd. While the application of goat manure 40 tonnes/ha increased N-total and C-organic. The results of the analysis showed that the parameters of pH H2O, pH KCl and Ca-dd correlated very strongly with P-available and had an effect of 70% at a depth of 0-30 cm, while at a depth of 30-60 cm the parameters of pH H2O, pH KCl, Ca-dd correlated very strongly and BOT correlated strongly with Pavailable and had an effect of 67%. In the N-total parameter, BOT and C/N are very strongly correlated. BOT and C/N influenced the N-total content by 99.4% at a depth of 0-30 cm and by 99.5% at a depth of 30-60 cm.
