Growers have also reported an apparent difference in the growth of pears under mulch. The full effect of the mulch on this crop will not be obvious until it is harvested at the end of February. As part of the project, an extensive carrot trial has been carried out in Virginia. This trial was important in helping growers to determine just how much compost could be applied without having a detrimental affect. Mr. Buckerfield said the trials have shown that while the application of large quantities of mulch may not be beneficial, lesser quantities can improve the quality of the carrots.
Improved quality means much more of the crop can attract premium prices.
Researchers will continue to monitor the effect of the added organic matter when the plot under carrots is planted to potatoes. Early indications are looking positive for capsicums too with a 25 per cent increase in the growth of capsicum plants in the first six weeks after compost application. Harvest will continue for some months to confirm whether this also results in a substantial increase in crop yields. Flowers will be harvested three times a week over the next three months to determine the effects of green organics on the quality of blooms throughout the season. Mr. Buckerfield said the next step was to determine the economic benefits to each of the growers using composted green organics on their crops.
