Buggy source:
@Override public ISeedRequirements getSeedRequirements(ItemStack seed){
  if (SeedHelper.isValidSeedStack(seed)) {
    SeedRequirements result=new SeedRequirements();
    GrowthRequirement growthRequirement=GrowthRequirements.getGrowthRequirement((ItemSeeds)seed.getItem(),seed.getItemDamage());

        result.setSoilBlock(Lists.newArrayList((IBlockWithMeta)new BlockWithMeta(net.minecraft.init.Blocks.dirt)));
        result.setNeedsTilling(true);
      }

Fixed version (ground truth):

  if (CropPlantHandler.isValidSeed(seed)) {
    SeedRequirements result=new SeedRequirements();
    GrowthRequirement growthRequirement=GrowthRequirements.getGrowthRequirement((ItemSeeds)seed.getItem(),seed.getItemDamage());
    result.setNeedsCrops(ConfigurationHandler.disableVanillaFarming);
    if (growthRequirement.requiresSpecificSoil()) {
      if (growthRequirement.getSoil().getBlock() == net.minecraft.init.Blocks.farmland) {
        result.setSoilBlock(Lists.newArrayList((IBlockWithMeta)new BlockWithMeta(net.minecraft.init.Blocks.dirt)));
        result.setNeedsTilling(true);
      }
 else {
        result.setSoilBlock(Lists.newArrayList((IBlockWithMeta)growthRequirement.getSoil()));
        result.setNeedsTilling(false);
      }
    }
 else {
      result.setSoilBlock(new ArrayList<IBlockWithMeta>());
      result.setNeedsTilling(false);
      for (      BlockWithMeta elem : GrowthRequirements.defaultSoils) {

          result.setNeedsTilling(true);
        }
 else {
