[QUOTE="Lancrop Laboratories, post: 6943666, member: 148905"] [B][SIZE=7]Do you know your soil pH?[/SIZE] Impact of soil pH[/B] Soil pH is a measure of acidity or alkalinity of the soil, it has a direct effect on nutrient availability, microbial activity and overall plant health. A knowledge of soil pH is fundamental to soil and crop management. [ATTACH type="full"]879956[/ATTACH] [B]Managing soil pH[/B] Agricultural crops, pastures, vegetables and fruit crops are grown in a wide range of soil pH. However, all species have a preferred pH range for optimum growth. Getting the pH wrong can have a significant effect on crop yield and quality, largely as a result of reduced nutrient availability. Soils become acidic from natural processes, such as weathering and leaching, and the change can be accelerated by climate, plant species and agricultural practices, meaning soil pH should be monitored at regular intervals. Fertilizer application can also accelerate the development of acidity, particularly urea and elemental S fertilizers. Liming is the only way to neutralise the acidity. The lime requirement depends on soil texture, crop and soil pH. The speed and duration of the effect depends on other factors e.g. quality (%NV), particle size and mode of incorporation. There is little that can be practically done to reduce pH in alkaline soils but the timing and form of fertiliser applications can be adjusted to ensure an adequate supply of nutrients. [B]Soil pH and soil organisms[/B] The ability of, and rate at which, micro-organisms break down organic matter and convert soil nutrients, including nitrogen, into plant available forms is directly influenced by soil pH. Bacterial populations and activity decline at low pH levels, whereas desirable fungal activity can drop off as pH levels rise and the common earthworm will not survive at all in very acidic soils less than pH 4.5.
