Pengaruh Teknik Penggenangan Tanaman Padi Terhadap Beberapa Sifat Kimia Tanah

Abstract

Abstrak. Penggenangan tanah sawah akan menyebabkan serangkaian perubahan beberapa sifat kimia tanah. Penelitian ini bertujuan untuk mengetahui pengaruh teknik penggenangan tanaman padi terhadap beberapa sifat kimia tanah. Penelitian ini dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Syiah Kuala Darussalam Banda Aceh yang dimulai sejak Juni sampai November 2017. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) pola Non Faktorial. Perlakuan yang dicobakan adalah Teknik Penggenangan Tanaman Padi (P) yang terdiri atas 4 taraf dengan 4 kali Ulangan, sehingga percobaan ini mempunyai 16 satuan percobaan. Parameter yang di amati antara lain, pH tanah, P-tersedia, N-total, Fe, dan DHL. Hasil penelitian ini menunjukkan bahwa teknik penggenangan pada tanaman padi berpengaruh sangat nyata terhadap Fe dan DHL tetapi tidak berpengaruh nyata terhadap pH tanah, P tersedia dan N total.Effect Of Environmental Rice Planting Techniques Against Some Properties Of Land ChemicalsAbstract. Flooding of paddy fields will lead to a series of changes in some soil chemical properties. This study aims to determine the effect of rice cropping techniques on some soil chemical properties. This research was conducted in Experimental Garden of Agriculture Faculty of Syiah Kuala University of Darussalam Banda Aceh which started from June to November 2017. The design used in this research is Completely Randomized Design (CRD) Non Factorial pattern. The experimental treatment is Rice Flotation Technique (F) consisting of 4 levels with 4 times Deuteronomy, so this experiment has 16 unit experiment. Parameters observed include, soil pH, P-available, N-total, Fe, and DHL. The results of this study indicate that flooding techniques in rice plants have a very significant effect on Fe and DHL but no significant effect on soil pH, P-available and N total.

Effect of Bio-Organomineral Fertilizer on Soil Chemical Properties and PB Content of Industrial Waste Polluted Soil

“…The decrease in pH was caused by the accumulation of CO2, which was produced when microorganisms broke down organic matter. CO2 reacted with water to form H2CO3, which dissociated into H + and HCO3 - (Munandar et al, 2018).…”
