Planning for Success of your Next Crop or Pasture

The most productive crops or pastures require a successful plant establishment, but that all depends on timely rainfall, right? Sure, sufficient moisture is fundamental, but there are levers you can pull in your operation to better manage your fallows and best prepare for planting to increase the chances of success from your next crop or pasture. Here are some elements for you to consider, and how each might affect your operation.

  • Maintain ground cover and soil moisture: During rainfall events groundcover slows the speed of surface runoff allowing more time for infiltration. Ground cover and old crop residues help protect the soil from erosion during heavy summer storms. This is particularly important on steeper slopes or drainage lines where there is an increased erosion risk. There are numerous benefits to soil biota and soil organic carbon levels associated with maximising the amount of ground cover in your farming system.
  • Decision to till the soil should always be well considered: Avoiding the use of tillage in fallow management enables you to benefit from ground cover in the system. At times tillage may still be required in our modern farming systems to provide another mode of action to kill weeds reducing the reliance on herbicide and the risk of herbicide resistance within weed populations, to ameliorate soil surface compaction, to incorporate lime or other surface spread fertilisers, to disrupt the life cycle of pests and other diseases or to prepare a seedbed when access to no till machinery is not available.
  • Know your planting equipment: Know what machinery you intend to use to plant and understand its limitations. Manage your fallows accordingly to increase the chances of successful plant establishment.
  • Control your weeds: If you are using no till methods it is important to control weeds with registered herbicides used in accordance with the product label. Farming systems should not rely on just one mode of action to kill weeds as this will inevitably result in herbicide resistance within the weed population. Herbicides from different chemistry groups with varying applications should be used. In some circumstances two separate herbicides applied in two separate spray applications on the same weeds may be required. This approach is commonly referred to as a ‘double knock’. Some herbicides have a residual effect in the soil and different crops vary in their tolerance to residual herbicides. Producers need to adhere to plant back periods for different crops and pastures to ensure that plant damage does not occur.
  • Nutrition: Soil tests can give a good indication of the status of major nutrients in the soil. Leaf tissue testing of previous crops is better to determine levels of trace elements. It is important to understand the soil nutrient levels and future crop or pasture requirements well in advance of planting to ensure appropriate fertiliser management strategies are implemented.
  • Select appropriate species: Give consideration to climate, soil type and its limitations, grain markets or stock feed requirements, machinery and other infrastructure available when selecting crop or pasture species. Any species planted in unsuitable growing conditions is destined to fail. Generally, newer plant varieties have increased production traits and pest and disease ratings, but better agronomic practices with regard to fallow management, nutrition, planting equipment, timeliness of operations and grazing management will have a far greater influence on productivity than varietal choice alone.
