To a great extent your farm’s productivity, and therefore its profitability, rests upon your soil(s). With the cost of fertilisers and their application, eating into your profits, soil testing is an essential farming tool. When assessing your Soil(s) Nutrient Status, it is important to measure the existing soil fertility status before changing anything, . . . → Read More: Soil Nutrient Status and Soil Testing Understanding the evolution of soils and landscapes is very important for an understanding of the behaviour of soils under various forms of land use. This article details how soil and its’ components arrived at your place, and how some of it moved on. Soil formation is closely connected to other landscape processes such as . . . → Read More: Soil - a dynamic process of change Soil is the basis of production for a farmer. The way soil is tilled, grazed, drained, added to and detracted from can be micro-managed to some extent. You cannot prevent flood, nor the removal of topsoil by high winds during drought, but you can gain a deeper understanding of how your everyday farming activities . . . → Read More: More ways to investigate your soils A New Zealand farm producing wheat and barley on the Waimea Plains, was experiencing very different growth and harvest rates in wheat fields where the same management processes were undertaken. The farmer was unsure of the reason(s) and determined to find out why. With the assistance of the Topoclimate South Pedologists he attained a . . . → Read More: Soil Structure; a case study Farmers have a significant problem with soil vulnerable to structural collapse, particularly when there is a combination of prolonged heavy rains and vulnerable soils. As part of the Topoclimate South Soil Mapping Project, we devised a simple index from the mapping data that we were gathering that gave a quick guide to farmers of the . . . → Read More: Soil Structural Vulnerability Index or SVI Maintaining a good soil structure is far cheaper than rectifying a damaged one. A good soil structure will reward a farmer, or a gardener, many times in increased production,ease of tillage and lower irrigation costs. Soil structure refers to the grouping of soil particles into aggregates. These aggregates are commonly called peds. In topsoils . . . → Read More: Why maintain good Soil Structure? |
