ABSTRACT OF THE DISCLOSURE Culturing an algae with known flocculant production capability on the soil for the purposes of aggregating soil particles is disclosed. According to the disclosure flocculant producing algae are grown in liquid culture as disclosed in United States Patent No. 3,958,364. The nitrogen in the culture medium is maintained so that cellular nitrogen does not fall below 10%. The algae are then inoculated onto soil which is provided with supplemental nutrients and moisture sufficient to produce a multiplication on the order of several hundred fold. The nutrients other than nitrogen are provided in sufficient quantity to permit a further period of growth during which algal flocculants are produced which have the property of binding soil particles into workable aggregates.
