Soil properties on organic farms favor a greater diversity in weed species and reduced weed pressure compared with conventional farms ( Ngouajio and McGiffen, 2002 ). Despite the reduced weed pressure, weeds are frequently cited as the most

collected and processed from 10 Aug. 2020 to 25 Jan. 2021. Seventy-five smallholders were randomly selected from the county’s planting list; their basic information is shown in Table 1 . We investigated the yield, soil properties, farmer agronomy practices

suitability will differ for other species. However, researchers should proceed with caution when extrapolating correlative results between soil properties and weed distributions, especially for weeds with a wide geographic distribution. The effects of

spectrometer (Thermo Jarrell Ash, Franklin, MA). Data analyses of yield data sets were performed using one-way analysis of variance in Quattro Pro 10. Results The soil properties at the four locations were distinctly different. Overall, Beaumont

are as soil amendment and organic fertilizer for horticultural crops. Application of compost can improve soil properties such as organic matter, water and nutrient storage capacity, aggregate ability, resistance to compaction and erosion, infiltration

Marketing Service, 2012 ). Many studies support opinions held by producers that increases in SOM enhance physical and chemical soil properties and management practices that favor the aggradation of SOM result in plant growth and productivity benefits

fertilizer per year to ensure large and colorful flowers. These management measures inevitably affect soil properties and microbial ecology. Soil biological and biochemical properties have become increasingly recognized as important for assessing the

’ Satsuma mandarin scion on different rootstocks in calcareous soil were measured. We examined soil properties and physiological parameters in plants, such as leaf nutrition, chlorophyll concentration, Fe concentrations in plants, and the transcription
