Lahan pantai termasuk ke dalam kategori lahan marginal karena kandungan unsur hara yang rendah dan keterbatasan air maka diperlukan pembenah tanah dan teknologi irigasi sehingga menjadi lahan produktif pertanian. Tujuan penelitian ini membandingkan interaksi antara jenis irigasi serta konsentrasi pupuk kandang terhadap sifat kimia tanah serta menemukan hubungan antara EC tanah dan kadar lengas tanah pada lahan pasiran pantai Bantul. Penelitian menggunakan demplot dengan ukuran 1 x 1 m, 2 perlakuan irigasi (Sprinkler/Sp dan Kabut/Kb), 5 konsentrasi pupuk kandang (kontrol/0, 5 kg/m2, 15 kg/m, 10 kg/m2, dan 15 kg/m2). Komoditas yang ditanam adalah sawi hijau (Brassica juncea L.) dan dilakukan dua kali penanaman. Total ada 30 demplot percobaan dalam sistem Rancangan Acak Kelompok (RAK). Parameter yang diuji meliputi kandungan C-Organik, pH tanah, Electrical Conductivity (EC), dan kadar lengas tanah. Data dianalisis melalui uji normalitas dan homogenitas (p > 0,05), dilanjutkan dengan uji ANOVA (p < 0>

Coastal land is categorized as marginal land due to low nutrient content and limited water, so soil conditioners and irrigation technology are needed to make it productive agricultural land. The purpose of this study was to compare the interaction between irrigation type and manure concentration on soil chemical properties and to find the relationship between soil EC and soil moisture content on pasiran land of Bantul beach. The research used a demonstration plot with a size of 1 x 1 m, 2 irrigation treatments (Sprinkler/Sp and Mist/Kb), 5 concentrations of manure (control/0, 5 kg/m2, 15 kg/m2, 10 kg/m2, and 15 kg/m2). The commodity planted was green mustard (Brassica juncea L.) and two plantings were conducted. There were a total of 30 experimental demonstration plots in a Randomized Block Design system. Parameters tested included C-Organic content, soil pH, Electrical Conductivity (EC), and soil moisture content. Data were analyzed through normality and homogeneity tests (p > 0.05), followed by ANOVA test (p < 0>
