NITROGEN - MANAGING NUTRITIONAL RISK AND INVESTMENT IN WESTERN DOWNS CROPS NITROGEN – MANAGING NUTRITIONAL RISK INVESTMENT IN CROPS

Plain text source: 
Climate variability (inter- and intra- season rainfall and temperature patterns) and prices received for grain of a particular quality make it very difficult to offer serious strategies to optimise profitability in the short term... There are two periods of the year when nitrogen application offers the greatest likelihood of recovery of applied nitrogen in winter cereals: around the end of the calendar year and in July (GS 3.2) according to studies over approximately 10 years starting in the late 1970's, over six No-Till sites in by Felton and Marcellos... Nitrogen costing about $1.40 per kilogram, operating costs greater than $310 per ha, grain yields averaging 2.2 tonnes per ha and grain prices sub- $180 for grain (at depot), make it difficult to 'make ends meet'...
