| dc.description.abstract | Biological amendments influence soil pH, which is shaped by former land use. pH is a measure of hydrogen ion concentration that impacts the nutrient acquisition of plants. The variation in soil pH affects ecosystems differently; forests tend to be acidic due to the presence of enzyme-producing fungi, while grasslands lean towards alkalinity from enzymes produced by alkaline favoring bacteria. Synthetic fertilizers, over time, acidify soils, affecting nutrient uptake. This study investigated the impact of biological and synthetic nutrition treatments on soil pH in vineyards. Applying compost, compost teas and extract for the biological treatment over four months in the summer of 2022. Soil samples were collected bi-monthly, and pH measured using standardized protocols. Results revealed differing effects of the treatments on pH in former forest and field lands. Statistical analyses demonstrated significant pH changes in synthetic-treated fields, while treatments-maintained pH within optimal ranges for grape vines. These findings could be in part to the soil microbiology and recent land conversion that significant influences on pH dynamics. Continued research is warranted to understand the long-term effects of nutritional amendments on soil pH in dynamic ecosystems. | |
