In the course of the cropping season, there is often not enough rain or a sudden halt to the rainy season, and meteorologists often get it wrong, according to Coffi Sedjvo Elvis Padonou of Promotion Jeunesse Unie in Abomey, Benin. He feels that the damage to the ozone layer, caused by pollution or natural phenomena, could be blamed. In any case, for farmers it is difficult to obtain good harvests in this situation, since not everybody has the means to irrigate their fields. 'But to save your harvest, you can also harrow your field every 2 weeks or, if possible, every week. By harrowing, you can easily make good use of the water-holding capacity of the soil and can bridge these difficult periods, even if it means extra expenses. We experienced this result several times in our own agricultural practice.' Quite right, Coffi, even if your advice raised a few eyebrows here in the office. Farmers know best after all! Harrowing after tillage seals the open soil and breaks the evaporation of moisture in the freshly broken soil. Harrowing especially in the case of a crust breaks the capillary action that releases the moisture from the soil. So harrowing can indeed improve the water-retention capacity of the soil and limit evaporation.
