beside the hay, I've already seen ads of alfalfa bales and bales of pea ...
on occasion, is it a good alternative to hay?

but that was before the Didite ...

We would have to have analyzes to answer with precision and certainty.

These are legumes, which are fundamentally much richer in nitrogen than hay (which consists only of a dominant of grasses).

Alfalfa hay may, despite the development of more fibrous, thicker stems, be a little richer in nitrogen. The quality of alfalfa hay is very variable depending on how it was done: often, tedding operations cause the small leaflets, which are particularly rich, to fall.

It's probably the same for pea leaves ...

These will probably be good materials, a little too rich in nitrogen, that it would be possible to "dilute" with poorer materials: dead leaves, wood chips, hemp straw ...

The big defect of the two materials will probably be the fact of being too coarse: even in rather thick layer, it will let the light pass - and therefore the covering effect will be less; more risk of developing weeds ...

I visited a sheepfold in Aveyron, for alfalfa, the operator cut it green enough, and did not press it, he kept it in a dryer above the sheep, if not from the explanations too much loss in quality, he also praised the goods made on the decompacting soil, he used a crop rotation with a mixture of grasses and others and thus had much better results than his neighbors
so like Didier if it's alfalfa hay pressed, I do not think it's interesting the useful paries will remain on the ground, the pea hay will be very rude, but if as Didier think it is richer in Nitrogen on a damaged ground I will put BRF and top of the pea hay, for improved a ground to come
for the land to be cultivated this season, the hay will remain the best solution, let's not forget that we must sow, plant in this layer of vegetal cover
