Abstract

Soil quality becomes poor with the use of inorganic chemical fertilizers and pesticides. Some efforts have been made to improve the quality of the soil, but naturally, not much has been studied. Natural improvement of soil quality by using Trichoderma and biochar and applying them to the cultivation of lettuce vegetables has not been reviewed, so it needs to be studied. This research aims to improve soil quality with Trichoderma and biochar and trial it on the cultivation of lettuce vegetable plants. The study was conducted by analyzing the chemical properties of the soil two weeks before being planted with lettuce. At the time of planting with lettuce is fertilized with Trichoderma and biochar, at the planting age of 2 weeks after planting, then the planting age after three weeks analyzed the quality of the soil again. To study the cultivation of lettuce, measurements of leaf length, plant height, Number of leaves, and plant weight at the time of harvest. The results showed an improvement in soil quality, from a soil pH of 5.52 to a pH of 7.8 N levels; 0.16%, K exchange;0.32 and P available; 4.32 ppm is better. Lettuce plants grown in soil treated with Trichoderma and biochar fertilizers showed greater yields than lettuce plants not treated with Trichoderma and biochar fertilizers. This research could improve soil quality for the foreseeable future using Trichoderma and biochar fertilizers.

Abstract

Kulitas kimia tanah menjadi buruk karena pemakaian pupuk kimia dan pestisida yang berulang-ulang pada lahan yang sama. Perbaikan kualitas tanah sudah banyak dilakukan, seperti dengan menggunakan zeolite, atau campuran zeolite dengan TiO2, atau dengan menggunakan arang tempurung kelapa saja. Penggunaan arang tempurung kelapa dengan campuran pupuk organic cair dari Lamtoro belum banyak dipelajari. Tujuan penelitian adalah Memperbaiki kualitas kimia tanah yang sudah sering diperlakukan dengan pupuk kimia dengan menambahkan arang dari tempurung kelapa dan pupuk organik cair lamtoro pada budidaya wortel. Penelitian ini ada 2 jenis yaitu Analisa laboratorium mengenai Analisa Kualitas kimia tanah dan penelitian lapangan untuk budidaya tanaman wortel. Pengukuran pH menggunakan pH meter, penentuan, P tersedia dan K dengan metoda Olsen sebelum perlakuan , dan metode Bray setelah perlakuan.  Penentuan N dengan metode Kjedahl. Budidaya wortel dengan Rancangan Acak Kelompok (RAK) denga 5 perlakuan dan 4 kelompok. Dianalisis secara statistika dengan uji F. Kalium tanah naik dari 0,20 me/100 g, termasuk rendah menjadi sedang yaitu 0,45 me/100 g 1 kalimat, P tersedia naik   dari 13,1 menjadi 19,1 serta N dari 0,2 menjadi 0,3  , pH naik dari 5,2 menjadi 6,1. Secara umum kualitas tanah menjadi lebih baik untuk budidaya wortel dimana perlakuan dengan penambahan arang 10 ton/ha dan konsentrasi pupuk organik cair (POC) daun lamtoro dengan konsentrasi 300 ml/L air mampu meningkatkan pertumbuhan dan hasil tanaman wortel.
