چکیده

یکی از راهکارهای اصلی بهبود شرایط فیزیکی خاک­های تحت کشت، اضافه کردن اصلاح­کننده­های آلی و معدنی به خاک می­باشد. اين تحقيق با هدف بررسي تأثیر سه نوع ماده اصلاحی شامل هومات­پتاسيم، پرمرغ و ورمي­کمپوست با درصدهای وزنی متفاوت بر روي خصوصيات فيزيکي خاک و در سطوح مختلف رطوبتي در شرايط مزرعه (تحت کشت گندم) اجراء گرديد. طرح به صورت فاكتوريل در قالب طرح پایه بلوك­هاي كامل تصادفي در سه تكرار انجام شد. مواد اصلاح­كننده به طور يكنواخت تا عمق 10 سانتي­متري با خاك مخلوط و تيمارهاي رطوبتي اعمال شد. قبل و بعد از آزمايش از کرت­ها نمونه­برداري به عمل آمد. پارامترهاي فيزيكي شامل: جرم مخصوص ظاهري (Bd)، رطوبت­های ظرفيت مزرعه­اي (FC) و نقطه پژمردگي دائم (PWP)، پايداري خاكدانه­هاي مرطوب (WAS)، هدايت هيدروليكي اشباع (KS)، مقاومت فروروی (PR)، شیب منحنی رطوبتی در نقطه عطف (Si)، میانگین وزنی قطر خاکدانه­ها (MWD) و بعد فراکتالی جرمی خاکدانه­ها (Dm) محاسبه گردید. نتايج نشان داد مصرف مواد­آلی موجب کاهش Bd (89%) و افزایش FC ،PWP (87% و 91% ) Ks و WAS (7/3 و 5/2 برابر) می­گردد. با افزایش سطوح رطوبتی و مقدار ماده­آلی بخصوص هومات­پتاسیم، میزان Si کاهش یافت (101%). PR با افزایش سطوح رطوبتی کاهش یافت. بر خلاف انتظار با افزایش میزان ماده­آلی،Dm  و MWD کاهش یافت. مواد آلی در زمان­های طولانی­تر و در رطوبت­های بالا موجب بهبود پایداری خاکدانه­ها می­گردد. با توجه به تأثیر مثبت مواد آلی بر بسیاری از پارامترهای فیزیکی خاک، این مواد بخصوص پرمرغ بعلت ارزان‌تر و دردسترس بودن، برای اصلاح خاک­ها پیشنهاد می­گردد.
