Balansa has good levels of hard seed which allow balansa clover to regenerate well after a season of cropping... Mid and late maturing varieties of balansa clover are commercially available, and this range allows the species to be grown in areas receiving between 350 and 800 mm of annual rainfall... Balansa clover grows best in monoculture; good performance with perennial grasses or short-lived ryegrass has been reported...

Our GRDC-sponsored research aimed to quantify the economic value of the five SOI phases system (see note below) for tactical nitrogen management at mid-tillering in wheat in south-eastern Australia, and also to provide guidelines to improve profits without increasing the level of risk through exposure to climate variability... The study showed that higher profits, without increasing the level of risk of economic loss, can be achieved by adopting a seasonal forecasting system to determine the doses of nitrogen to be applied in split nitrogen applications between pre-drill and tillering...

WA growers adapt to changing rainfall patterns.. Dr Stephens says earlier sowing has benefits for crops, as they experience lower evaporative demand through the growing season and appear to be less affected by declining rain in October and increasing spring temperatures... During the growing season, Dr Stephens says changing climate will also require adaptation of input strategies and changes to crop disease and pest risks, especially with more summer rain creating 'green bridges'...
Current farming systems expose farmers to heavy losses during good seasons when the risk of crop failure is low and returns could be maximised by additional levels of N... The SOI phases, originally developed in Queensland, can be used to identify a set of past years of similar climatic characteristics (analogue years) to the present season... Seasonal climate forecasting is a crucial tool for growers to micro-adjust and governments to macro-adjust economic strategies and policies to reduce impacts on private, estate and national economic objectives...

Graph two is for a heavy clay Black Vertosol from Spring Ridge; results show the plant available water capacity (PAWC) is 272mm... Rooting depth should be determined through perusal of physical and chemical data and the physical observation of roots and water extraction through soil coring and/or electronic monitoring... Simulation of water storage using the >100 year climate record shows that a short fallow from wheat (assuming a dry soil profile at harvest in November of the previous year) results in a 50% chance of at least 110mm (range of 0-300mm) of water being available for an April planting at Spring Ridge and 80mm (range of 0-180mm) at Nyngan (Figure 8)...
