Predicting profitability of summer weed control timing and impact on crop yield potential: $ummer
Summer fallow weed control has been shown to be an integral component of modern crop production systems in a changing Australian climate. At the same time suboptimal control of summer weeds have been shown to have high continuing cost to yield and profitability. Field trial results are used to show the importance of the soil water and nitrogen drivers of the impact of summer weed control timing options under different soil and weed scenarios. A predictive tool ($ummer) designed to inform summer weed control investment decisions including the impact of timing options is presented.
