Digging deeper : an evaluation of field quality for agricultural use

Abstract

The aim of this project is to evaluate the agricultural quality and crop yield potential of a private field located in central Malta, through the use of soil and on-site assessments. The core research question guiding the investigation is: What is the agricultural quality and value of the field based on its soil characteristics and site conditions, and which crops is it best suited for? To answer this question, both qualitative and quantitative data was gathered by doing field observations and taking soil samples. Soil tests were carried out to find out the texture, electrical conductivity, nitrate level, phosphorus level, pH level, salinity, and metals availability. The site's topography, sun exposure, drainage, water availability, and how the land around it is used were also looked at. The soil had a clay loam texture, with a clay content of about 34%. At 0.26 dS/m, the electrical conductivity was low, suggesting low salinity and ideal growing conditions for most crops. Calcium was present at about 332 mg/kg and nitrate levels were 5 ppm, this suggests an average amount of nutrient availability. However, challenges like seasonal waterlogging and mild compaction in some places were noted and may have an impact on productivity. According to the analysis, crops like tomatoes, bell peppers, and zucchini make good crop choices for the field.
