If at any time the Secretary has reason to believe that in the case of cotton, or rice the operation of farm marketing quotas in effect will cause the amount of such commodity which is free of marketing restrictions to be less than the normal supply for the marketing year for the commodity then current, he shall cause an immediate investigation to be made with respect thereto. In the course of such investigation due notice and opportunity for hearing shall be given to interested persons. If upon the basis of such investigation the Secretary finds the existence of such fact, he shall proclaim the same forthwith. He shall also in such proclamation specify such increase in, or termination of, existing quotas as he finds, on the basis of such investigation, is necessary to make the amount of such commodity which is free of marketing restrictions equal the normal supply.
If the Secretary has reason to believe that, because of a national emergency or because of a material increase in export demand, any national marketing quota or acreage allotment for cotton,1 or rice should be increased or terminated, he shall cause an immediate investigation to be made to determine whether the increase or termination is necessary to meet such emergency or increase in export demand. If, on the basis of such investigation, the Secretary finds that such increase or termination is necessary, he shall immediately proclaim such finding (and if he finds an increase is necessary, the amount of the increase found by him to be necessary) and thereupon such quota or allotment shall be increased, or shall terminate, as the case may be.
In case any national marketing quota or acreage allotment for any commodity is increased under this section, each farm marketing quota or acreage allotment for the commodity shall be increased in the same ratio.
