Potential of goat manure as organic fertilizer in North Sumatera

Abstract

The North Sumatera province has the fifth largest goat population in Indonesia after Central, East, Lampung and West Java. Meanwhile, solid and liquid goat manures have great potential as a source of organic fertilizer. Therefore, this study aims to examine the potential of goat manure as a source of organic fertilizer and its role in improving soil quality, growth and crop production. The data were collected from the Central Bureau of Statistics and the results of previous studies. Furthermore, the potential of goat manure was calculated by multiplying the total goat population in North Sumatra by the goat manure production /head/day and converted to one year. The parameter measured was the total goat population in North Sumatera, goat manure production/head/day, and the covered agricultural land area. The results showed that goat manure only fulfilled 3.69% of the agricultural land area in North Sumatera. In addition, the case study in Deli Serdang District showed that the application of goat manure compost with biourine and balanced inorganic fertilizers increased red chilies’ productivity by 46%. Therefore, it was concluded that the potential of goat manure as organic fertilizer is still very low.

Respons pertumbuhan dan hasil tanaman kedelai hitam (Glycine max (L) Merril) terhadap berbagai konsentrasi biourine dan pupuk KCl

“…Biourine telah banyak digunakan dalam budidaya berbagai jenis tanaman diantaranya sawit (Jamidi et al, 2023), pisang (Sulistiyani & Napoleon, 2022), cabai merah (Batubara et al, 2021) dan lain-lain. Akan tetapi, belum banyak penelitian yang melakukan uji coba budidaya terhadap tanaman kedelai, peluang pengembangan tanaman kedelai baik dari segi ketersediaan lahan dan varietas unggul.…”

“…Banyak varietas unggul yang tersedia, namun tidak seluruhnya sesuai untuk dibudidayakan. Potensi urin kambing untuk memenuhi kebutuhan pupuk organik lebih besar dibandingkan dengan kompos yang ditunjukkan pada produksi dan kontribusi unsur hara (Batubara et al, 2021). Selain penggunaan pupuk cair untuk meningkatkan unsur hara dalam tanah untuk pertumbuhan tanaman kedelai, pupuk cair biourine dan pupuk K bekerja sama untuk mempercepat pembukaan dan penutupan stomata melalui peningkatan aktivitas turgor sel.…”

“…Biourine yang digunakan ialah biourine yang memiliki potensi terbaik yaitu urine kambing (Batubara et al, 2021). Aplikasi biourine dilakukan setiap satu minggu sekali yang dimulai pada umur 14 hst hingga tanaman berbunga, yang diberikan lewat tanah dan tanaman yang disemprotkan pada daun kedelai setengah liter dan setengah liternya ke tanah.…”

Morphological Performance of Edamame Applied by Livestock Manure in Acid Dry Land

“…The more soil fertility increased, the more resilience nutrients dynamic in soils for the purpose of improving crop productivity. [24] in their research stated that goat manure compost and biourine combination showed an increasing yield up to 46% on red chilies in Deli Serdang district, North Sumatera with the dose of organic and inorganic fertilizers according to farmers habitus. Organic and inorganic fertilizers combination (semi-organic farming) also the alternative application chosen by farmers to increase crop qualities and productivity.…”

Effect of goat manure levels on growth performance of wild watermelon (Citrullus lanatus var. Citroides) cultivated under shade house conditions

“…It is still shameful that manure is not usually put on agricultural land in Sub-Saharan African (SSA) nations (Washaya and Washaya 2023). There is no literature on increasing wild watermelon yields, even though numerous studies on the use of goat manure as soil fertility have been conducted (Ansah et al 2019;Batubara et al 2021;Mbatha et al 2021;Köninger et al 2021), but very few have used. Thus, the study aimed to determine the effect of different goat manure levels on the growth yield and performance of wild watermelon (Citrullus lanatus subsp.)…”
