Abstract

Narathiwat Province ranks third in Thailand for the number of goat farmers. Improper manure management can cause livestock disease and odor pollution, whereas appropriately managed manure is a potential nutrient source for the province’s nutrient-poor sandy soils. This study combined a field experiment on a sandy Ban Thon soil, arranged as a randomized complete block design with five treatments and five blocks (control; goat manure at 3.5 t rai⁻¹ [21.9 t ha⁻¹]; chemical fertilizer based on soil analysis plus 2.0 t rai⁻¹ goat manure; goat manure at 4.0 t rai⁻¹; and chemical fertilizer alone) with a purposive survey of 90 goat-integrated farms assessing manure supply, use, and gross fertilizer replacement value. After 75 days, chemical fertilizer plus manure produced the highest mean sweet corn fresh shoot biomass (mean ± standard deviation, 612.6 ± 55.4 compared with 150.5 ± 18.8 g plant⁻¹ in the control), significantly exceeding manure at 3.5 t rai⁻¹ (425.9) and chemical fertilizer alone (320.6 g plant⁻¹) but not differing significantly from manure at the farmer-practice rate of 4.0 t rai⁻¹ (535.5). Because the combined treatment received the full mineral fertilizer rate plus manure, this result reflects a greater total nutrient input and does not demonstrate synergy or fertilizer substitution. Post-harvest soil pH, available phosphorus, and exchangeable potassium were higher in manure-containing treatments than in the control and chemical fertilizer alone (exchangeable potassium 58.5-82.4 compared with 5.2-18.5 mg kg⁻¹). The surveyed farms produced an estimated 75,686 kg air-dry manure year⁻¹, a potential coverage of about 4.5% (2-11% across scenarios) of the estimated manure demand of their cropland, with a first-year gross fertilizer replacement value of about 107,500 Baht year⁻¹. Goat manure therefore appears best used as a supplement to, rather than a replacement for, mineral fertilizer; multi-season trials are needed to confirm yield and long-term soil effects.
