Hay as mulch to provide a moisture bonus, implemented the same way as the "slow fertilizers"

[Guimoute]

I believe that would add educational value to the nice agriculture system we already have, and be a fun optional game mechanic. Those who do permaculture IRL will agree.

Right-clicking farmland with a dry grass item in hand should apply a layer of hay to it, providing a small moisture bonus (say 10%) and arguably a few percents of nitrogen. It would have an overlay texture similar to what is found in the `Vintagestory\assets\survival\textures\block\soil\fertilizer` folder, except it would be a bit fuller on the first stages, maybe slightly 3D. The moisture bonus would decay the same way slow fertilizers decay.

100% agree, as a permaculturist, we need to be able to find mulch either from the forest like leaves or spread compost, hay, manure on our soil so it gets better with each application and retains moisture longer.

Heres an example of a garden I built by only spreading organic matter like forest litter, grass clippings and fallen leaves directly onto my yard and it grews into a beautiful veggie garden without any maintenance as long as it rains once or twice a month.

Hay as mulch to retain moisture would be a great improvement to farming in hot climates.

Very good idea, it would totally fit with the game!

I agree with you all, although not a must have right now, including mulching to the game could provide many advantages to the player on top of refining the gardening experience.  Let's also not forget some of the other added benefits of straw mulching :

1. Helps retain heat in the winter and protects from overheating in the summer (through less evaporation).  It is a soil temperature regulator.

Straw mulch can decrease the rate of evaporation by 35% (Russell JC (1939) The effect of surface cover on soil moisture losses by evaporation).  This could be simulated in-game with a better water retention after rainfall, going from 100% to standard soil humidity a third slower; also frost and overheating protection by a few degrees.

2. Increase harvest output up to almost 50% in some cases.

The following table provides various data.   The improvement in the economic yield of various crops due to mulching

 

With so many advantages I feel it would be necessary to ensure the mulching process is not something straight forward to do as a player.  Maybe ensuring the hay is properly dried before applying so it doesn't turn into rot on the crop; Maybe making the receipe for hay much harder (9 grass instead of 4?); Any other idea?

Perhaps make mulch take a specified amount of time before it turns into compost?  Forget to check the mulch and find it's turned to compost.  Maybe make the mulch window a couple of days in length?

Hay would be great to use on onion crops and garlic if we had it.

Hey, I know this thread dates back a bit, but I just wanted to let you know that I've taken the mulching mechanic from Crops V2 by Emmett_chef and put it into its own mod. It does exactly what was suggested, using grass as mulch to keep the moisture in. Here's the link: https://mods.vintagestory.at/show/mod/34989
