Like many natural assets our soils get neglected. Last year brought record levels of flooding and waterlogging. As a result shortages of oxygen encourage deleterious anaerobic microbes. These microbes solubilise nutrients that are leached from the soil,they form toxic organic compounds and increase acidity.
These damaged soils demand careful husbandry aiming at restoring structure and fertility.
Once the land drains start aeration. Restore fertility with manure, compost and lime if required.
Lawns will need aeration and moss control. Fertiliser should be lower in nitrogen with increases of potassium and phosphorus.
