Root health issues
Due to the very mild autumn many crops are advanced for the time of year, with little signs of cold weather growth is expected to continue. whilst on the surface this is a good thing, underground is very differant. we are seeing brown rust appearing on foliage along with mildew and septoria in wheat, rhynchosporium and net blotch in Barley and Phoma , light leaf spot in Oilseed rape crops. all these diseases cause an abiotic reaction within the plant. add to this colder and wetter soil conditions and we begin to see phosphate and Magnesium being restricted in availablity. crops growing a good foliage are empty of nutrition to match. roots suffering from nutritional deficiency and abiotic conditions will not develop correctly, and if the roots are not present the plants can not access nutrition when it demands it, possibly leading to wasted, or leached nutrients. The key here when we think of soils is to keep air in the ground, which reflects back to how we created the seed beds, soil chemistry and the soils biology. maintaining a viable root system through the winter is one key area in achieving a succesful crop.
