Expodireto Special: Embrapa shows the impacts of soil compaction

In this edition of Expodireto, which takes place from 5 to 9/03, in Não-Me-Toque, RS, Embrapa presents the results in the management of compacted soil in the area installed in the fair's technology showcase. Practices to alleviate the problem increased yields by 124,7% in soybeans and 148,6% in corn.

To show the effects of compaction on grain production, three treatments were carried out on the soybean and corn plots exposed at last year's Expodireto. See the results in the table below:

	Soil Type	Soybean and corn sowing	income sc/ha	Gain
Treatment 1	compressed	seeder equipped with discs only	Soy 29,9 Corn 62,1	comparative
Treatment 2	Compressed	Seeder equipped with deep shank	Soy 50,5 Corn 89,9	Soy + 68>#/p### Corn + 44>#/p###
Treatment 3	Unpacked with scarification	seeder equipped with discs only	Soy 67,2 Corn 154,4	Soy + 124,7>#/p### Corn + 148,6>#/p###
