Case Studies

Investing in long-term soil amelioration yields significant economic benefits. Improved soil health leads to higher crop yields and better quality produce, translating into increased farm profitability. For instance, a study revealed that liming acidic soils resulted in a benefit-cost ratio of up to ... read more

Addressing soil constraints requires tailored amelioration strategies. For acidic soils, liming is an effective solution. Lime applications neutralise soil acidity, increasing pH levels and enhancing nutrient availability. Studies have shown that liming acidic soils can increase crop yields by up to ... read more

Accurate diagnosis of soil constraints is essential for effective management. Identifying soil acidity involves testing pH levels using soil samples collected from different depths. A pH of less than 5.5 is typically considered acidic, requiring lime applications to neutralise the acidity. Regular s ... read more

Soil constraints pose significant challenges to Australian agriculture, limiting crop productivity and economic returns. Common issues include soil acidity, compaction, salinity, and sodicity. These constraints hinder root growth, reduce nutrient availability, and impede water infiltration, leading ... read more

Over the next four weeks, we'll look into the topic of soil constraints their impact on agricultural productivity, and how OPTISOIL can be the preferred partner to unravelling these opportunities. Soil constraints like acidity, compaction, salinity, and sodicity can severely limit crop yields and fa ... read more

Optimising Nitrogen placement in flood furrow irrigated Cotton, designing a sampling strategy to investigate lateral nitrogen movement in flood furrow cotton fields.  Background  The Challenge: A cotton grower recently switched from banding anhydrous ammonia to broadcast urea nitrogen (N ... read more

Background The Challenge: Farmers in Glenmorgan faced a daunting task. Their fields were riddled with deep gilgai formations, known locally as “melon holes”, making spraying, planting, and harvesting highly inefficient. These formations impeded machinery movement and caused waterlogging ... read more

In the diverse agricultural landscapes of Wimmera, VIC, farmers face a recurring puzzle: a significant yield gap that varies spatially each year. This article delves into the challenges posed by soil constraints, specifically alkalinity and dispersion, and explores innovative solutions being impleme ... read more

We recently had the opportunity to work with a client from Walgett, who faced significant challenges on his property following a flood. As a dryland farmer, the season following a flood presents something of an opportunity with a full moisture profile. Grower observations/problem The client notice ... read more
