Poultry farming involves the production of poultry manures (PMs), which, if properly managed, are excellent organic soil amendments. Poultry farms generally do not have adequate arable land, and therefore, valuable fertilizer becomes a problematic waste. During the production and storage of PMs, odorous VOCs, NH, HS, and potent greenhouse gases such as CH, CO are emitted. It influences the productivity of poultry and negatively affects the working conditions of working staff. In the present study, mineral-microbial deodorizing preparations (MMDP) based on perlite and bentonite as well as the following microorganism strains , , , , and were added to the litter of turkey broilers (TB) and egg-laying hens (LH). PMs were compared with treatments without the addition of MMDP, and maize, sunflower, and rapeseed forage crops were tested. The influence on soil parameters such as pH, EC, HAC, SBC, CEC, BS, N, C, and plant yield and parameter of photosynthesis, i.e., SPAD index, was tested. Soil amending with manure resulted in an increase in pH and a decrease in HAC; in addition, an increase in EC, which was counteracted by the addition of MMDP, was noted. MMDP positively affected parameters such as SBC, CEC, and BS. It was shown that PMs, with the addition of MMDP, improved crops' yield in the first year of the study, whereas this effect was not seen for the after-crop plants (lupine). The main 'added value' related to the usage of MMDP in poultry production is the improvement in the properties of PMs, which mainly had a positive effect on soil indicators.
家禽养殖涉及家禽粪便（PMs）的产生，如果管理得当，这些粪便将是极好的有机土壤改良剂。家禽养殖场通常没有足够的耕地，因此，有价值的肥料变成了有问题的废物。在 PMs 的生产和储存过程中，会排放出有臭味的挥发性有机化合物（VOCs）、氨（NH）、硫化氢（HS）和强效温室气体，如甲烷（CH）、二氧化碳（CO）。这会影响家禽的生产力，并对工作人员的工作条件产生负面影响。在本研究中，向火鸡育雏（TB）和蛋鸡（LH）的垫料中添加了基于珍珠岩和膨润土的矿物-微生物除臭制剂（MMDP）以及以下微生物菌株 、 、 、 、 。将 PMs 与未添加 MMDP 的处理以及玉米、向日葵和油菜饲料作物进行了比较。测试了其对土壤参数（如 pH 值、电导率、酸可提取碳（HAC）、可交换性缓冲容量（SBC）、阳离子交换能力（CEC）、有效缓冲容量（BS）、氮（N）、碳（C）和植物产量以及光合作用参数，即 SPAD 指数的影响。施用粪便会导致 pH 值升高和 HAC 值降低；此外，还观察到电导率增加，而添加 MMDP 可抵消这种增加。MMDP 对 SBC、CEC 和 BS 等参数有积极影响。结果表明，添加 MMDP 的 PMs 提高了研究第一年作物的产量，而对后茬作物（羽扇豆）则没有这种效果。在禽畜生产中使用 MMDP 的主要“附加值”是改善 PMs 的性质，这主要对土壤指标产生积极影响。
