Triticum compactum or incomplete specimen. As a general rule, if a naked wheat, wheat with round grains and irregularly broken rachis forming internodes, is uncovered in a European site, excluding all sites on the Italian or Balkan peninsulas, it should be considered a hexaploid club wheat (either "T. aestivum" or "T. compactum" ). If such wheat has short internodes it should be identified as "T. compactum". "Triticum compactum" generally flowers during the months of June and July with its seeds ripening in August and September. "Triticum compactum" is an annual plant growing to heights of approximately 0.6 meters in the summer and
Crop residue whereas cereal straw would reduce next year's soil supply of available nutrients. Over time, the nutrients fixed by soil microbes and humus are released and available to crops. Nutrients from residue are not fully recovered by crops. Just like fertilizer nutrients, nutrients released from crop residue into the soil are susceptible to losses such as leaching (N and S), denitrification (N), immobilization (N, P, K and S), and fixation (P and K). The efficiency of nutrient uptake by crops from fertilizers or residue release is generally thought to be similar. For example, about 50 percent recovery of N in the
